Smith–Magenis syndrome

Quick Reference

A set of complex developmental abnormalities affecting a wide range of neural, skeletal, and organ systems. Caused in most cases by a deletion in chromosome 17p11.2, but can also be caused by mutations in the RAI1 gene (retinoic acid inducible-1) and a milder phenotype is associated with duplication of the same chromosomal region.
