Treatment options for XXYY syndrome
A study by UC Davis M.I.N.D. Institute and The Children's Hospital in Denver described the medical and psychological characteristics of a rare genetic disorder in which males have two "X" and two "Y" chromosomes, rather than the normal one of each. Senior author Randi Hagerman, who holds an endowed chair for fragile X research, said the study found a variety of behaviors, learning disabilities and emotional problems that are unique to patients with XXYY syndrome that may be better addressed with more targeted therapies. The study was published in the American Journal of Medical Genetics Part A.
