Summaries for 48,xxyy Syndrome

NIH Rare Diseases : 53 48,XXYY syndrome is a chromosomal condition, characterized by the presence of an extra X and Y chromosome in males, that causes medical and behavioral problems. 48,XXYY can be considered a variant of Klinefelter syndrome. Individuals with 48,XXYY are usually considerably tall with small testes that do not function normally leading to infertility. In addition, affected individuals have behavioral problems such as anxiety, aggressiveness, problems communicating, hyperactivity, depression, as well as general learning disabilities and intellectual impairment.  Other medical probelms can include congenital heart defects, bone abnormalities, tremor, obesity, type 2 diabetes and/or respiratory problems. Patients have an essentially normal life expectancy but require regular medical follow-up.

MalaCards based summary : 48,xxyy Syndrome, also known as xxyy syndrome, is related to 47, xxy and precocious puberty. An important gene associated with 48,xxyy Syndrome is POMC (Proopiomelanocortin). The drug Testosterone has been mentioned in the context of this disorder. Affiliated tissues include heart, testes and bone, and related phenotypes are inguinal hernia and azoospermia
