Chromosome 15q trisomy
Chromosome 15q trisomy Definition
Chromosome 15q trisomy is genetic disorder wherein the end of the long arm of chromosome 15 (15q) appears thrice instead of only twice in the body cells. This results to growth delays either before or after birth as well as mental retardation and malformations in the head and face. Other abnormalities are a short neck, disfigured fingers or toes, scoliosis and other skeletal malformations. Males with this condition suffer from genital problems, and cardiac illnesses. In most cases, Chromosome 15q trisomy is a result of a translocation of chromosome balance in one of the parents.
