Nicolaides-Baraitser syndrome (NCBRS) is a very rare condition characterized by severe intellectual disability and various physical features. Signs and symptoms may include seizures, short stature, sparse hair, distinctive facial characteristics, short fingers and toes (brachydactyly), and prominent joints in the fingers and toes (interphalangeal joints). Features of the condition can worsen over time. NCBRS is caused by changes (mutations) in the SMARCA2 gene and is inherited in an autosomal dominant manner. All cases reported to date have been sporadic, occurring in people with no family history of NCBRS.
