Chromosome 15q duplication is an extremely rare genetic disorder in which there is an excess copy of the long ("q") arm of human chromosome 15.
Signs and symptoms
The disorder is primarily characterized by growth abnormalities, which range from growth retardation to accelerated growth, intellectual disability, and distinctive malformations of the head and face. Additional abnormalities may involve malformation of the skeleton, spine and neck; fingers and/or toes; genitals (particularly in males); and, in some cases, heart problems.[1][2]
Diagnosis
Treatment
The condition is incurable and treatment is based on alleviating symptoms.[1]
Epidemiology
C15 trisomy affects twice as many males as females. Fewer than 50 cases have been reported.[1]
