About the ACRC Clinics

Since 2015, the scientists and researchers of the AXYS Clinic and Research Consortium (ACRC) collaborate, share information, and explore opportunities to participate in joint research projects. In addition, AXYS organizes annual meetings of the consortium where members meet to discuss topics important to the X & Y variation community.
Types of Clinics
Due to the many X & Y Chromosome variations, not all clinics specialize in all conditions. Below is a listing of ACRC clinics. The specific conditions and patient ages served by the clinic are noted in the description.
Multidisciplinary Clinics
Some clinics use a multidisciplinary approach, offering medical, psychological, and therapy services in one visit. Providers collaborate to create coordinated care plans and may offer take-home materials for local professionals. Check each clinic’s website or ask when scheduling to understand its specific services.
Note: Anyone planning to visit an ACRC clinic should check with the specific clinic and their insurance provider to see if they have coverage

Board and Staff
AXYS Board of Directors and staff members are dedicated to the mission of AXYS and to our X and Y variation community. While election to the board is an honor, members also have important legal and fiduciary responsibilities that require a commitment of time, skill and resources. The ideal board member is strongly committed to AXYS’s mission and vision, and has the interest, skills, and resources that will fuel the organization’s growth.
Officers
Chair since 2024, Director since 2024
Your name: Ginnie Cover
Your connection to AXYS: XXY, but have written about all variations
General location: Mid- Atlantic (Washington DC metro area)
How long have you been with AXYS? Since 1995 (originally KS&A)
Brief professional bio: Ginnie worked throughout her career with children and adults with complex medical conditions and developmental disabilities. She holds an MSW from the University of Michigan. After her now adult son was prenatally diagnosed with 47,XXY, in the 1980’s, pre-internet, Ginnie became an advocate for those with X and Y chromosome variations, providing educational programs for families and for professionals who work with this population. In 2012, she published Living with Klinefelter Syndrome, Trisomy X, and 47,XYY, a widely read guidebook to X and Y chromosome variations. During the pandemic, she turned to fiction, completing a novel, Supplemental Needs, about a family coping with a prenatal diagnosis. Ginnie wrote this novel because disability in children is rarely portrayed in fiction, and certainly not where there is a prenatal diagnosis involved. She is a past Board member, and returned to the AXYS Board as Chair in 2024. Ginnie and her husband, who are the parents of two adult sons, live in the Washington, D.C., metro area.

Prenatal Testing
Our Helpline (1‑267‑338‑4262 or helpline@genetic.org) volunteers and support parents give priority to providing information to expectant parents.
A non-invasive prenatal blood test (NIPT) on the mother only suggests a risk that the fetus has an extra X or Y chromosome. It is not a diagnosis. Follow up is needed.
Amniocentesis (a needle inserted into the uterus to draw out fluid-containing cells surrounding the fetus) and chorionic villus sampling (CVS, in which a small sample of the developing placenta is taken) can both show whether extra chromosomes are for certain present, and can serve as a definitive diagnosis.
After prenatal testing, it is always worthwhile to consult a genetic counselor. The National Society of Genetic Counselors have an online directory.
Watch this video on prenatal tests.
Children with X or Y variations are unlikely to have severe developmental disabilities. These genetic conditions tend to involve speech delay or learning disability, not profound delays that prevent independent living. Many families find that early intervention and special education services minimize the impact of the extra chromosome.
AXYS is pleased to provide you with the following letter written by a parent of a child with Klinefelter syndrome, but relevant to all parents of a child with an x or y variation:
I am writing this letter to parents who have received a prenatal diagnosis of sex chromosome aneuploidy (SCA), one or more extra X and/or Y chromosomes. First, I want to tell you that I have been in your shoes, having learned at 18 weeks pregnancy that I was carrying a boy with an extra X chromosome… Read entire letter

A Letter to Expectant Parents
Dear Parents:
I am writing this letter to parents who have received a prenatal diagnosis of sex chromosome aneuploidy, meaning that your child has one or more extra X and/or Y chromosomes. First, I want to tell you that I have been in your shoes, having learned at 18 weeks pregnancy that I was carrying a boy with an extra X chromosome, a condition known as Klinefelter syndrome, or 47,XXY.
I also know that this diagnosis is an indescribable shock, and that it causes great apprehension for your child’s future. You may even have been told that you need to make a decision, quickly, about whether or not to continue with this pregnancy. So let me tell you a little bit of my story.
My son is now 25. He lives independently in an apartment, he drives, he can work, and he has also had girlfriends and hopes to get married in the future. I can tell you, however, that he had substantial delay in developing speech as a young child, along with low muscle tone and poor coordination, which is fairly typical of many children with X and Y chromosome variations. He responded well to early intervention, and largely caught up with his peers. Although he has an IQ in the normal range, he has significant learning disabilities and received special education services during school. He did, however, play violin and received a number of musical awards.
He is also kind, and compassionate, and has a great sense of humor. He plays golf and badminton, and although he dropped out of college in his second year because of his learning difficulties, he has determined that he now has the maturity to return, obtain the extra help that he needs, and complete a degree.
If I were to characterize John’s functioning on the “spectrum” of sex chromosome aneuploidy (SCA), I would say that he is squarely in the middle of the bell curve. There is enormous variation in how these children and adults present. In perhaps one-third of kids, there are no learning disabilities and few other complications or signs of the syndrome. In the other two-thirds, there can be mild to moderate learning disabilities, but intellectual disability is rare.
Most adults with SCA establish themselves in careers and live independently. Many have satisfying relationships and become parents. Most adults will tell you that while it took them a bit longer to become independent than their peers, they have had good lives, even though they may have had some struggles in childhood and adolescence.
I can’t tell you specifically what to expect. I can tell you that parenthood is always both a joy and a challenge and that the mild or moderate disabilities that may be present in children with X and Y chromosome variations are manageable. These conditions are not devastating, either to the child or to his or her family.
When you know about the condition before birth, you have a great advantage. Without prenatal diagnosis, these conditions often cause such subtle symptoms that diagnosis and the therapies that can minimize developmental difficulties are delayed, sometimes by years. Children with SCA often are remarkably responsive to early intervention therapies, and to special education programs that target their difficulties with reading and with verbal and written expression.
When you are aware of the specific deficits that SCA may cause, you can more quickly qualify your child to receive the services that he or she needs. When parents are committed to learning about SCA and address developmental and learning difficulties promptly with effective therapies, potential problems can be minimized.
More good news: AXYS is committed to assisting families in helping their children live successfully with X and Y chromosome variations. The organization also provides substantial and ongoing support and education for adults with SCA. This website features a number of resources that summarize some of the childhood manifestations of SCA, and provide you with a listing of resources so you can learn as much as possible about X and Y chromosome variations.
Finally, I want to emphasize that these conditions are surprisingly common, affecting 1 in 500 children. You do not need to feel that you are coping with this news alone; our community is there for you to provide support and education that will help you promote your child’s development and well-being.
Yours sincerely,
Virginia Isaacs, MSW
