PLACK syndrome (OMIM 616295) is a form of generalized peeling skin syndrome (GPSS; OMIM 270300). It is an autosomal recessive genodermatosis caused by pathogenic mutations in CAST , which encodes calpastatin, an endogenous specific inhibitor of calpain, a calcium‐dependent cysteine protease. We present a 5‐year‐old girl diagnosed with PLACK syndrome with typical clinical features and homozygosity for a novel variant.
