Learning and Brain Development in Boys with Klinefelter Syndrome
Description:

This interdisciplinary research study is specifically designed to increase our understanding of learning, behavior, genetics, and brain development in Klinefelter syndrome (KS). We are recruiting boys between the ages of four and ten years, who have non-mosaic KS (47XXY, as confirmed by standard karyotype).

Study participation consists of three components: 1) a comprehensive neuropsychological and behavioral evaluation using standardized assessments, 2)  magnetic resonance imaging (MRI) scans of the brain, and 3) a blood draw of 30mL from patients and parents. It is important to note that MRI scans are considered to be safe for use with children, and carries no greater risk than everyday activities, such as playing sports or riding in cars. There is no sedation used for MRI scans in this study.

This study is conducted at Stanford University in California and will comprise of one visit. Participants and their families will be provided a report of the neuropsychological evaluation, with the option of an individual consultation with our PI, Dr. Reiss, to address questions or concerns. Participants will also take home a detailed picture of their brain scan as a souvenir.

Our study covers the cost of travel, lodging, and a meal stipend for participating families for the duration of their time at Stanford.

EFFECTS OF TESTOSTERONE THERAPY IN YOUNG ADOLESCENTS WITH KLINEFELTER SYNDROME (47,XXY)
Description:

 This study will study the effects of testosterone therapy on behavior, mood, problem solving, attention span, and motor skills in adolescent males with Klinefelter syndrome in early puberty. During this period in early puberty there is a lot of variability in how and when doctors start testosterone therapy. This study will evaluate if there are benefits to starting testosterone therapy in early puberty.

Participants with Klinefelter syndrome in early puberty (around age 10-15) will be treated with either testosterone gel or a placebo (inactive) gel and followed for 1 year. Participants will be followed for changes in behavior, emotions, cognitive abilities, executive functioning, motor skills (strength, balance, coordination), and physical features (pubertal development, body habitus, gynecomastia).

This study is conducted in Denver and includes 5 visits over 1 year. Study assessments include IQ and executive function assessment, motor skills assessment, and behavioral questionnaires completed by the participant and caretakers. The testing is conducted in two sessions of approximately 3 ½ hours each over 1-2 days during select visits. Participants are provided with the study medication and gift cards as a token of appreciation. Travel to Denver, Colorado may be provided.

Assessments are completed as part of the research study, and a summary of research testing results will be provided.

Evaluating the Effect of X/Y Chromosome on Immune System Health
Description:

This study will evaluate the effects of X and/or Y chromosome variations on the health of your immune system. Immune system defends us against all kinds of pathogens including bacteria, fungi and viruses, and provides surveillance against cancer.  However, sometimes our defense system revolts against our own body, resulting in conditions called autoimmune diseases that affect every organ system in our body. Interestingly, many genes that can profoundly affect our immune system are located on X chromosome. Autoimmune conditions are also 2-13-fold more prevalent in women (XX) than in men (XY). Hence, it is imperative to assess the health of our immune system in individuals with variations in X and/or Y chromosomes.    

We will perform a detailed evaluation of immune system in individuals with X/Y variations (XXY, XYY, XXX, X0, mosaics, or any other X/Y variation). In order to find out whether X/Y variations affect immune system health, we will need to perform a simultaneous assessment of immune system in individuals with 46,XX women and 46,XY men, who will ideally be matched for ethnicity and age+/- 5 years, and friends or acquaintances of individuals with X/Y variations. We request that everyone with this condition try to participate in the study, so that the results of study are representative of the X/Y variations

Participation involves each subject completing a confidential questionnaire – online https://ctq.ctrl.ucla.edu/ctq/login/ or paper version. We request that participants also provide a blood sample – that can be collected by coming to UCLA, at KS&A meetings, or by shipping collection packets to any location without expense to participants.

Blood samples from pregnant women carrying a fetus with a sex chromosome abnormality are needed!
Description:

The goal of this study is to develop a prenatal blood test that can diagnose genetic disorders in the fetus by looking at fetal DNA (genetic material) found in the mother’s bloodstream during pregnancy.  If successful, this will reduce the need for invasive testing during pregnancy and allow women to find out accurate information regarding their baby’s health early in the pregnancy.

Who is eligible?

  • Women and their partners (presumed biological father of the fetus) who are currently pregnant and carrying a fetus that has been diagnosed with Turner syndrome, Klinefelter syndrome, Triple X Syndrome, or 47,XYY.

What do I need to do?

·      The mother and biological father (if available) will be asked to provide a blood sample.  There will be 4 tubes collected from the mother (approximately 3 tablespoons) and 1 tube collected from the father (2 teaspoons).  The samples will be collected at no cost to the couple. 

·      What are the benefits?
Neither subjects nor their doctor will receive any results from the study.  Therefore, there is no direct benefit from participating.  This study and the subjects who participate may help other women in the future if the study results in a new test available to pregnant women. 

Each couple will receive $100 for their participation.

Brain Development and Learning Difficulties in Klinefelter Syndrome and Trisomy X/Triple X Syndrome
Description:

Volunteers needed for a
Brain and Cognition Research Study

The MIND Institute at University of California, Davis is carrying out a study on the problems that some children have with thinking and reasoning about time, space, numbers and related areas of learning. The study is funded by the National Institutes of Health, which is the main organization that gives money for research in the United States. Dr. Tony Simon would like to invite your 7 to 14-year old child with Klinefelter syndrome or TrisomyX/Triple X syndrome to be part of the study. Many children with Klinefelter syndrome or TrisomyX/Triple X syndrome score lower on language-based tasks compared to visuospatial skills. We are studying the brain and how it produces this kind of thinking. Once we know more, we plan to develop interventions to reduce learning problems in children with certain genetic conditions.

Children who take part in the study will play computer games, do paper and pencil tests, and have pictures taken of their brain using an MRI machine. MRI scans do not involve any radiation. All of the activities are safe and have been pre-Approved by our Institutional Review Board. As part of this clinical research study, IQ achievement testing is carried out and parents will receive a letter describing the results in the mail a few weeks after completing the study.

Testing can be completed in two sessions of approximately 3 1/2 hours each day (or one full day). After successful completion of this, your child will receive $60 in gift cards to thank them for their time and effort. If needed, some funds may be available to assist families with travel accommodations to Sacramento, CA. If you would like to find out more about taking part in this study and helping us learn about mind and brain development in children like your own, please contact one of the clinical research coordinators at The University of California, Davis MIND Institute at (916) 703-0408 or email us at cabil@ucdmc.ucdavis.edu.

CCUMC Cohort Study of boys between the ages of 8 and 18 years

Renewed Call for Study Participants

Description:

The Division of Pediatric Endocrinology at Columbia University Medical Center continues to seek boys with KS (47, XXY) between the ages of 8 and 18 years for a study on growth & development, body composition, hormones, metabolic and psychosocial health factors. To be eligible, boys must be between the ages of 8-18 years, be English-speaking and able to read at the first grade level. In the event an affected (47 XXY) boy is unaware of his diagnosis, non-disclosure will be maintained as per the parent wishes. Since we are measuring affected and non-affected boys, participants may not be aware of whether or not they are affected.

Each participant will receive a free medical exam, blood tests and a $25 American Express gift card for his participation. Parking will also be paid by the study. This study is currently underway. For more information, please visit our study website: http://www.47xxyklinefelteryouth.com or contact Sharron Close at 914-420-4508 for enrollment or for more information about this research opportunity.

UCLA Study Concerning the Effect of the X-Chromosome on Determining Sexual Orientation
Description:

Dr. Eric Vilain, Director of the UCLA Center for Gender-Based Biology, leads an interdisciplinary team of biologists and psychologists who are seeking to better understand the role that parental origin and skewed inactivation of the X chromosome may play in determining sexual orientation. This study seeks to correlate the parental origin and X-inactivation profile of the X chromosomes with the sexual orientation of the individual, and specifically to compare the genotype and X-inactivation profile of homosexual men with heterosexual men. Dr. Vilain and his staff are currently recruiting adults (18 and over) who are 47,XXY or 48,XXYY (either heterosexual or homosexual) to participate in this research project.

Participation involves each subject completing a confidential questionnaire and providing a saliva sample. If possible, and with the express approval of the subject, a second saliva sample may be requested from the subject’s parents. Collection packets will be shipped to any location without expense to participants, and participants will be compensated for their time.

Psychological and Motor Effects of Testosterone Therapy in Adolescents
Description:

Dr. Nicole Tartaglia, a pediatrician at The Children’s Hospital in Denver, is conducting a study in adolescent and young adult males with 47XXY, 48XXXY, 48XXYY, and 49XXXXY on the psychological and motor effects of testosterone therapy during puberty. Males who are beginning testosterone therapy will be evaluated to determine changes in learning, behavior, emotions, and motor skills before and after testosterone therapy. The study will also evaluate genetic factors that influence the features of the X and Y chromosome variations, and how genetic factors may influence the response to testosterone therapy. The study is recruiting adolescent males with 47XXY, 48XXXY, 48XXYY, and 49XXXXY who are starting on testosterone therapy. Assessments will be made before each adolescent begins therapy, and then again one year after therapy was begun.

During the year, families and patients will complete behavioral questionnaires at 3 and 6 month intervals. Testosterone replacement can be prescribed by the clinic, or by an outside endocrinologist (as long as it is possible to obtain medical records). Blood draws will also be required as part of the study to conduct genetic studies, to measure testosterone and LH levels. Children with received a $10 gift card for each study visit. Assessments will take place at Children’s Hospital.
