Signs and symptomsEdit

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]


The condition is incurable and treatment is based on alleviating symptoms.[1]


C15 trisomy affects twice as many males as females. Less than 50 cases have been reported.[1]
