Targeted syndrom under study
ACTL6A (MIM*604958)/Coffin-Siris syndrome (CSS)/NicolaidesBaraitser syndrome (NCBRS)
Variants in the actin-like 6A (ACTL6A; MIM*604958) gene have been associated with a developmental disorder with variable craniofacial dysmorphisms and congenital defects. Interestingly, the p.R377X variant has been found to cause a specific BAF-opathy phenotype, with clinical features reminiscent Coffin-Siris/Nicolaides-Baraitser syndromes. So far, a very limited number of patients has been reported. The identification of more affected individuals will better define the entire clinical core of the disorder and the associated genotype-phenotype correlations. Moreover, considering the possible skin involvement in the BAF complex-related disorders, the cutaneous phenotype will be also delineated.
