Deletion 3q21 Research
We recently identified mutations in the gene GATA2, located on chromosome 3q21, as a
cause of hereditary predisposition to myelodysplasia and myeloid leukemia. Others have
since shown that mutations in GATA2, in addition to causing familial forms of
myelodysplasia and leukemia, are also associated with congenital lymphedema and low
monocyte counts, predisposing to certain infections, including mycobacterial infections
related to tuberculosis. Subsequently, we have identified several patients with small
chromosomal deletions, including GATA2, in which some or all of these features, plus
additional problems related to loss of other genes, are also present. Individuals with
3q21 deletions spanning the GATA2 gene should therefore be evaluated with an eye toward
a possible increased risk for myelodysplasia and leukemia as well as vulnerability to
opportunistic infections. Our laboratory has a University of Washington Institutional
Review Board approved protocol for defining genetic aspects of the disorder.

The Experience of a Diagnosis — Lessons From Parents of Children With
Rare Chromosome Deletions/Duplications
Individuals who have a child or are the legal guardian of an individual with
a rare chromosome deletion/duplication that have been diagnosed through
Microarray Comparative Genomic Hybridization (cgh or array cgh) are being
invited by a genetic counseling student at Sarah Lawrence College in Bronxville,
NY to participate in a study on their diagnostic experience. The goal of this study
is to take a look at the experiences of families, throughout the diagnosis process.
It is hoped that the results from this study will lay the groundwork for studies that
will try to better help genetics professionals guide families through the process
and better address their needs. If you agree to participate in this study, you will
complete a web-based questionnaire, which should take approximately 20
minutes to complete. There is no cost associated and all participants are free to
withdraw from the research at any time.

Autism/Intellectual Disability Genetics Research Study -
Autism and Genetics: What Do We Know?
The Developmental Disorders Genetics Research Program (DDGRP) is investigating
genetic and molecular mechanisms underlying autism and intellectual disability.
We use genome–wide strategies to identify patterns in genes and chromosomes
that may be associated with these disorders.
The long–term goal of this research is to improve genetic diagnosis and
treatments, with the hope of improving outcomes for affected individuals.
We are inviting families to participate if there is at least one member affected
by autism or a related condition. Participation in the study consists of a
one–time interview during which we go over the individual’s medical
and developmental history, as well as construct a family tree. We may also ask
children to participate in a short evaluation. Finally, we will ask all family
members in attendance to provide a DNA sample. In the event that an in–person
appointment here in Rhode Island is not possible, we are also able to conduct
phone interviews and send families saliva collection kits for the purpose of
submitting a DNA sample via saliva.
By participating in the study, you can help future families like your own who
are affected by autism, and contribute to their diagnosis and treatment.

Molecular Study of Balanced X;autosomal Translocations
–in search of genes critical for intellectual disability and cognitive impairment
Medical College of Georgia in United States has been working on X;autosomal
balanced chromosome translocations to identify disrupted disease genes at the
The symptoms seen in the carrier of balanced chromosome translocation is
generally caused by a gene/genes disrupted at the one of the breakpoint of
translocation. So the aim of this study is to discover the genes on the X chromosome
that contribute to intellectual disability and speech delay by sequencing the
breakpoints of apparently balanced X;autosome translocations. Chromosome X
contains approximately 2000 genes and to identify which genes are at the breakpoints
on chromosome X will shed light on understanding the cause of this devastating
Intellectual disability (ID) is the most frequently reported developmental disability,
affecting cognitive function in about 1%–3% of people worldwide. A large
number of genes distributed throughout the genome are anticipated to cause ID
and more than 80 genes that cause syndromic and nonsyndromic ID have been identified
on chromosome X so far.
This study will lead the way towards greater understanding of the mechanisms how
intellectual disability and speech delay occur. Ultimately we aim to improve the
services and treatment to the affected families.
Most importantly, we will keep the families informed of progress made in our research
by telling which gene is disrupted at the breakpoint of the carrier of balanced
We are also willing to initiate molecular study of balanced chromosome translocations
not involving chromosome X as well to identify the cause of congenital anomalies.
We have already a couple of individuals participating in this study and there
is no cost for you to participate in this molecular research study. We will request
small amount of blood samples from you and available family members in order to
determine the breakpoint and parental origin of the translocation. We will pay
shipping costs by providing our Fedex number.
All participants are free to withdraw from the research at any time and will
be provided with updates on our research progress.

Research on Chromosome Abnormalities, Brain Malformations and
The Walsh Laboratory at the Children’s Hospital Boston and Beth
Israel Deaconess Medical Center is looking for genes involved in
brain development. We are currently enrolling individuals with
known chromosome abnormalities seen on chromosome microarray testing
and/or karyotype who also have brain malformations, such as
polymicrogyria, lissencephaly, Walker–Warburg syndrome,
heterotopias, and cerebellar hypoplasia, and inherited disorders of
cognition, such as familial mental retardation and familial autism.
Adults and children with these conditions, and their family members,
are invited to participate in our study. Examples of chromosome
regions currently under study include: 1q32, 1q42–44, 5p15, 6q21,
6q25, 6p25–6q27, 15q11–13, Xp22 as well as balanced and unbalanced
chromosome translocations and inversions.
Details we request to receive include copies of MRI images and
medical records, particularly the results of previous genetic
testing. Participation in our research involves providing a DNA
sample, usually by giving a small amount of blood, as well as
sharing information about medical and family history. We request DNA
samples from affected individuals as well as their parents and
healthy siblings, when possible. Reading and signing a research
consent form is required before enrollment.

Chromosome 13 study
A new research project to test children with chromosome 13
abnormalities by microarray to allow more precise definition of what
is deleted/duplicated and will identify all the genes in the
deleted/duplicated region. Since estimating which parts are deleted
using banding alone is somewhat inexact, sometimes even the
breakpoint of the deletion may change somewhat. The goal of our
study is to use the precisely defined chromosome 13 deletions or
duplications and the clinical features of the children to allow us
to deduce what genes are involved with what traits. This should
ultimately make prediction of outcome either prenatally or after
birth much more accurate, as well as to provide information to
parents on what would be the best medical care for their children.

Identification of a new gene involved in DiGeorge syndrome II at 10p13
1. Relevance to birth defects:
Congenital heart defects are the most common developmental anomaly and the leading
non-infectious cause of mortality in newborns. Conotruncal heart defects, which
account for 50-60% of all congenital heart malformations, are known to have a strong
genetic component. They occur either as an isolated malformation or in association
with extracardiac anomalies. In particular, conotruncal heart defects constitute
a cardinal component of branchial arch syndromes such as DiGeorge syndrome, whose
wide phenotypic spectrum includes cardiac defects, craniofacial dysmorphism, developmental
delay, hypoparathyroidism, genitourinary anomalies and T-cell immunodeficiency.
Although submicroscopic deletion of 22q11.2 or mutations of TBX1 within this region
is the predominant cause of DiGeorge syndrome, the genetic etiology in a subset
of DiGeorge syndrome patients is still unknown. Knowledge of the genetic basis of
DiGeorge syndrome II will provide insight into the role of a new gene in this disease
and then translate into clinical applications for genetic counseling and preconceptional
diagnosis to reduce the prevalence of birth defects.
2. Research objective:
We have solicited one Korean male DiGeorge syndrome II patient with a de novo heterozygous
deletion, 46, XY, del(10)(p12.3p14). Additionally we have acquired two lymphoblastoid
cell lines of two independent Caucasian female patients with 10p13 deletion as well
as 60 DNA samples from DiGeorge syndrome patients without a 22q11.2 or 10p13 deletion
or the causative TBX1 mutation. Preliminary comparative deletion mapping defined
a 2.5 Mb minimal critical interval that contains 19 genes. Deletion of 10p13-14
led to the hypothesis that DiGeorge syndrome II (MIM 601362) might be a contiguous
gene deletion syndrome. However, the frequency of observed deletions is extremely
low, suggesting that this disorder may result from mutations in a single gene in
the deleted region. So far no single obvious candidate gene for DiGeorge syndrome
II has yet been identified. Our goal is positional cloning of a new gene involved
in DiGeorge syndrome II by comparative deletion mapping with our deletion patients.
For this purpose we need more patients with 10p13-10p14 deletion or translocation
involving this region with overlapping phenotype of DGS to refine candidate gene
3. The hypothesis:
We hypothesize that a gene for DiGeorge syndrome II is located in this 2.5 Mb region
containing 19 genes at 10p13. So the fine deletion mapping with a comparative genomic
hybridization (CGH) array for the first time at 10p13 and FISH (fluorescent in situ
hybridization) will provide us with the identification of a positional candidate
gene at 10p13, which will be screened for mutations in DiGeorge syndrome or DiGeorge
syndrome-like patients, who do not have a 22q11.2 or 10p13 deletion or a TBX1 mutation.
We hypothesize that haploinsufficiency of a gene within the deleted region will
be the cause of DiGeorge syndrome II and we expect to find nonsense and missense
mutations in the patients with a normal karyotype and without a 22q11.2 or 10p13
deletion or a TBX1 mutation.

The Ring Chromosome 20 Foundation The Ring Chromosome 20 Foundation
is a lay advocacy organisation established to help connect patients and their families
with medical information and physicians specializing in Ring Chromosome 20 syndrome.
Ring Chromosome 20 syndrome (also known as r(20) syndrome) is a rare chromosome
disorder and for an unknown reason causes patients to have epilepsy, usually refractory
epilepsy (most devastating and difficult type to treat). Ring Chromosome 20 syndrome
is detected with a simple blood test. Since DNA testing is not a routine test when
epilepsy is first diagnosed, the foundation believes that r(20) syndrome is an under
diagnosed condition and many more people have it than would appear statistically.
The Ring Chromosome 20 Foundation is a registered Scottish charity and was founded
in 2003 by parents of a young child suffering from multiple seizures caused by r(20)
syndrome and the adverse side effects from certain anti-epileptic drugs. Their daughter
received a vagus nerve stimulator (VNS) to help control her seizures. With careful
use of antiepileptic medication in combination with VNS therapy, their daughter
has not had convulsive seizures in over two years. The Ring Chromosome Foundation
was created to help assist other families going through similar experiences by providing
information and a network of support. The purpose of the Ring Chromosome 20 Foundation
is to provide as much information as possible to families and patients with r(20)
syndrome. We work to connect patients and families to the best physicians, hospitals
and clinics in their area and around the world. The mission of the Ring Chromosome
20 Foundation is to help individuals with r(20) syndrome overcome the obstacles
they face so they might lead happy, healthy and productive lives. The foundation
funds research and medical assistance pertaining to Ring Chromosome 20 syndrome,
epilepsy and its treatment. Information on our website is also provided regarding
epilepsy, genetics, chromosome disorders and other related topics. If you have any

University of Washington Research Study: Chromosome 3p Deletions and Hearing
Loss The laboratory of Dr. Bruce Tempel at the University of Washington in Seattle
is currently investigating the cause of moderate-to-severe hearing loss seen in
many individuals with chromosomal deletions at or near the end of chromosome 3p.
We are looking for persons with or without hearing loss who have deletions on chromosome
3p to participate in our study. Background: Moderate-to-severe hearing loss is a
feature seen in many individuals with deletions on chromosome 3p. Our research has
led us to one particular gene that we believe is critical for proper hearing. If
one copy of this gene is lost due to a chromosomal deletion, we expect hearing will
be affected in a major way.
Why is this important? 1) Hearing may be overlooked in children with 3p deletions
because of other developmental delays. This greatly limits their ability to understand
and communicate with the world around them. Identifying the cause of this hearing
loss will allow care providers to catch hearing loss earlier in these children and
better tailor care to them. 2) It is quite possible the gene responsible for hearing
loss in 3p- individuals might also cause hearing loss in the general population.
Understanding the cause of hearing loss in 3p- individuals will also benefit many
others with hereditary hearing loss.
What is involved in participating? 1) A cheek cell swab from the person with the
deletion. We’ll send you special brush that is similar to a toothbrush. You rub
the brush on the inside of his or her cheek for 30-60 seconds and then send it back
to us. This is all we need to collect enough DNA for our study. 2) Permission to
look at his or her medical records. We’re looking for anything in the records about
hearing loss or none. We will pay for all postage and fees. You can do everything
at your convenience from the comfort of your own home. Patient confidentiality will
be strictly maintained. Participants will not be paid. If you would like, we will
follow-up with the results of our study. To participate or simply ask more questions,
please contact Brendan McCullough or Valerie Street at the HEAR group. We may be
reached by email: firstname.lastname@example.org

April 16, 2004 Ring 14
The chromosomal syndrome "Ring 14" consists of the partial
loss of genetic material from chromosome 14. It is characterized at the somatic
level by an involvement of many organs among which the central nervous system is
the major one in terms of clinical symptomatology.
The clinical symptoms of Ring14 syndrome, in fact, vary considerably
in each patient and are particularly represented by psychomotor delay, epilepsy,
retinal hyperpigmentation and a distinctive facial features.
Nevertheless, a precise definition of this condition is still lacking,
both at the genetic (genotype) and clinical levels (phenotype). This is essentially
due to the fact that cases are poorly described in the literature to be able
to analyse the associated symptoms in a statistically accurate way.
The rarity of the pathology and scarce knowledge of the clinical
symptomatology and its evolution are also at the basis of the few scientific studies
undertaken to search for the causes and the characteristics of the genetic damage,
of their role in determining the clinical picture. This also explains the
paucity of available therapeutic and rehabilitation tools.
Because of all of this, it is essential that detailed clinical and
genetic studies are undertaken that will allow for accurate knowledge of this rare
The clinical approach.
The first objective is the creation of a "database" to
collect details of cases highlighted nationally, Europe-wide and, subsequently,
worldwide. The database would hold a comprehensive details of the clinical
picture, instrumental and laboratory findings in order to bring a systematic
and global description of Ring14 syndrome.
The database, will be fulfilled with all the informations from electroencephalographic
(EEG), visual, auditory, somatosensorial Evoked Potential, neuroradiological findings
(RMN and Cat scan), and functional and metabolic neuroimaging (PET and SPECT) studies.
All these data should allow for increased knowledge of the specific areas of the
brain responsible for learning disability/intellectual impairment and epilepsy in
Ring 14 patients.
The genetic approach.
It is necessary to study the genotype-phenotype correlation in order
to understand the relationship between genetic cause (genotype) and somatic effect
Simultaneously, a clinical study will be undertaken to establish
the quality and the quantity of genetic material compromised in individual patients
and to correlate this with the clinical symptomatology, as well as examining the
parental origin (maternal or paternal) of the damaged chromosome 14 (imprinting)
and its role in the clinical symptomatology.
It is essential to remember that chromosome 14 is subject to "imprinting"
in humans: this means that some regions of this chromosome have different
functions depending upon the parental origin of the genetic material.
Throughout this project, detailed descriptions of clinical symptoms
and identification of the anatomical and functional defects of cerebral areas for
which we know the function (e.g. primary and associative areas for language), correlated
with the quality and quantity of damaged genetic material, will be examined. The
final priority of this study will be to set out the bases for our best understanding
of the illness, so that individualized, appropriate therapeutic and rehabilitative
strategies can be devised.
The project will use the expertise and existing medical and instrumental
resources in the centres of reference of medical specialists in the Scientific Committee
(Rome, Bologna, Reggio Emilia, Milan). It will develop in a first phase lasting
at least 2 years and requiring every form of collaboration and support in order
to bring it to realisation.

Individuals with a balanced chromosome translocation or inversion:
Researchers affiliated with Harvard Medical School are involved in a research study
to find genes that are important in human development. The Developmental Genome
Anatomy Project (DGAP) aims to study genes that have been altered by chromosome
rearrangements. In some individuals a balanced chromosome rearrangement is
associated with mental impairment and/or physical abnormalities. It is possible
that when the rearrangement occurred a gene (or genes) were broken or placed out
of order, resulting in developmental problems.
The focus of the DGAP investigation is to study the chromosomes and genes from individuals
with balanced chromosome rearrangements such as inversions or translocations who
also have physical abnormalities, disabilities, and/or mental impairment.
Such individuals are usually the first in the family to have a chromosome rearrangement
(the parents do not have the rearrangement and do not have the same medical problems).
Participation in DGAP involves giving a blood sample at your local doctor’s
office, reviewing and signing the consent form, and asking your doctor to provide
medical records. The identity of the participant and results are kept confidential.
It is hoped that the research will contribute to a better understanding of how the
human body grows and develops.

10p deletion research
Deletion 10p syndrome is not very well-characterized. The clinical features in some
previously reported cases reminiscent the phenotype of DiGeorge or Velocardiofacial
syndrome. However, the clinical findings are not consistent highly depending on
the size of the breakpoints of the deletion.
The aim of our study is to define the correlation between clinical observation and
the breakpoints of deletion both cytogenetically and molecularly. The information
gathered is important to be used a source of clinical information for the patients
and their families, as well as professionals.
We would like to contact with families and their physicians for participation in

11q balanced translocation/inversion
Dr. Paul Grossfield - pediatric cardiologist at UC San Diego (619) 543-5980
Dr. Paul Grossfield is on the faculty at the University of California, San Diego.
He is doing research on genetic causes of heart defects as well as mental retardation.
He has been studying intensively children with Jacobsen Syndrome, which is due to
a 11q terminal deletion. They have recently found the gene that causes the bleeding
problem in these children, and are looking for the gene that causes the severe,
sometimes fatal heart defects these children have, as well as mental retardation.
Specifically, Dr. Grossfeld is looking for any patient that has a heart defect and/or
mental retardation or any other serious medical problem, who has a balanced translocation
or inversion in 11q. In addition, Dr. Grossfeld is interested in ANY patient with
a balanced translocation or inversion in ANY chromosome.

13q especially kidney problems
Dr Abhay Vats from Department of Pediatric Nephrology at Children’s Hospital
of Pittsburgh would like to invite you to participate in their studies on
association of chromosome 13q with kidney problems. The main idea behind these
studies is to identify gene(s) located in the 13q region that are responsible for
proper development and functioning of the kidneys. Such studies can benefit
us by increasing our knowledge of the genetic conditions affecting the kidneys and
may in future lead to new ways of identifying and possibly treating such conditions.
Briefly, the kidney problems with 13 q deletion are not well known. Dr Vats’ group
has so far identified several children with 13 q deletion who have kidney
failure or protein in the urine or have malformations of urinary tract. One
child with 13q32 deletion has complete kidney failure and is on dialysis awaiting
kidney transplantation. Their work has led to identification of two critical regions
(on 13q22 and 13q32) that are associated with kidney diseases).
They would like to see if there are any other such children and investigate them
further in order to narrow down the areas in the 13q region that has kidney development
related genes. However, unlike many other organ systems, the kidney problems may
not be readily evident and there may not be any symptoms at all. These problems
are most often detected by doing a urine or blood test or a radiological investigation
(such as ultrasound of the kidneys). Many a times the kidney problem tends to worsen
with time and may only manifest as the child grows older. Hence, they would
like to know more about your child with 13q deletion and if he / she has been
found to have kidney problems. Also if no kidney related problems are known they
would like to investigate your child by a few simple tests including ultrasound.
If your child is found to have any kidney related problems, then, as part of the
studies a specimen of blood from your child and both the parents (and if possible
urine from your child) will be needed. The blood samples will be used to isolate
DNA to study various candidate genes.
The participation in these studies is entirely voluntary. All the research tests
will be paid for by them and we will bear the cost of any mailings, etc. Also, each
individual (ie parents and child ) will be required to sign a consent form for participating
in these studies. For further information please contact:

13q deletion, ring 13 and partial trisomy 13
Dr. Dorothy Warburton
22q11 deletions, translocation
We are announcing an IRB-approved study (Albert Einstein College of Medicine) on
chromosome rearrangements and mental retardation. Dr. Bernice Morrow and I here
at Montefiore Medical Center are particularly interested in persons who have chromosome
rearrangements involving the 22q11 region such as translocations, deletions (velo-cardio-facial
syndrome/DiGeorge syndrome, VCFS/DGS) or those who have a clinical diagnosis of
VCFS/DGS but not have a detectable deletion. If you have any patients who meet this
criteria, please contact me to discuss your case. Thank you.
