Joris Vermeesch, Raoul Hennekam and colleagues show that missense mutations in the SWI/SNF family member gene SMARCA2 cause Nicolaides-Baraitser syndrome, a disorder characterized by sparse hair, distinctive facial morphology, distal limb anomalies and intellectual disability. The mutations cluster to sequences encoding ultra-conserved motifs in the catalytic ATPase region of the protein and likely act in a dominant-negative or gain-of-function fashion.
