Comment when marking as ready: CHST8 rated as red by Expert review, and only one isolated case of Peeling skin syndrome described in OMIM and literature.
Created: 2 Dec 2016, 9:54 a.m.
In 7 affected members of a consanguineous Pakistani family segregating autosomal recessive noninflammatory peeling skin syndrome (PSS3; OMIM:616265), Cabral et al. (2012, PMID: 22289416) identified a homozygous c.229C-T transition (rs149660944) in exon 4 of the CHST8 gene, resulting in a R77W substitution. As David Kelsell states: this is the only reported mutation.
