Coffin Lowry Syndrome
Coffin Lowry syndrome is a rare genetic disorder characterized by
- mental retardation;
- abnormalities of the head and facial (craniofacial) area;
- large, soft hands with short, thin (tapered) fingers;
- short stature and/or
- various skeletal abnormalities.
Characteristic facial features may include an underdeveloped upper jawbone (maxillary hypoplasia), an abnormally prominent brow, downslanting eyelid folds (palpebral fissures), widely spaced eyes (hypertelorism), large ears, and/or unusually thick eyebrows. Skeletal abnormalities may include abnormal front-to-back and side-to-side curvature of the spine (kyphoscoliosis) and unusual prominence of the breastbone (sternum) (pectus carinatum).
Coffin-Lowry syndrome is caused by mutations in the RPS6KA3 gene and is inherited as an X-linked dominant genetic trait. Males are usually more severely affected than females.
