What are the signs and symptoms of X&Y Chromosome Variations?
The signs and symptoms of X&Y Chromosome Variations vary and depend on the number of extra X and/or Y chromosomes. While some individuals with X&Y Chromosome Variations go undiagnosed, signs of these conditions often include developmental delays, learning disabilities and behavior problems. Tall stature, small testicles, pubertal delays (for males with additional X chromosomes), speech delays, reading disabilities, ADHD, anxiety, mood instability and subtle physical traits can also be features in some children and young adults. Any of these features may lead physicians to recommend chromosome testing. Typically signs and symptoms of X&Y Chromosome Variations are more apparent in individuals with a greater number of X or Y chromosomes.
