Overview

Coffin-Siris syndrome is a genetic condition that causes variable degrees of learning disability, developmental delays, underdeveloped “pinky” toenails or fingernails, and distinct facial features. It can be caused by a change (mutation) in any of several genes including the ARID1A, ARID1B, SMARCA4, SMARCB1, or SMARCE1 genes. Coffin-Siris syndrome follows an autosomal dominant pattern of inheritance, however it usually occurs for the first time in a family due to a new mutation.[1] Occupational, physical, and/or speech therapy can help affected individuals reach their full potential.[2]
