condition with abnormal number of X or Y chromosomes
Sex Chromosome Aneuploidy refers to a condition where an individual has an abnormal number of sex chromosomes (X or Y) instead of the typical XX or XY. This can lead to various developmental and health issues, such as Turner syndrome (45,X) or Klinefelter syndrome (47,XXY). These abnormalities can affect physical development, fertility, and sometimes cognitive function.
