Clinical validity


Tsurusaki et al, 2012 identified de novo mutations in SMARCB1 in 2/5 individuals with CSS. SMARCB1 encodes a subunit of the SWItch/Sucrose Non-Fermenting (SWI/SNF) complex, and screening of additional genes encoding subunits of this complex revealed mutations in SMARCA2, SMARCA4, SMARCE1, ARID1A and ARID1B. Overall, Tsurusaki et al, 2012 identified mutation in 20/23 (87%) patients with CSS. Mutations in SMARCA2 have since been identified in patients with Nicolaides-Baraitser syndrome.
