Genes affected

TGM5 (HGNC:11781): (transglutaminase 5) This gene encodes a member of the transglutaminase family. The encoded protein catalyzes formation of protein cross-links between glutamine and lysine residues, often resulting in stabilization of protein assemblies. This reaction is calcium dependent. Mutations in this gene have been associated with acral peeling skin syndrome. [provided by RefSeq, Oct 2009]

The c.1922T>C (p.I641T) alteration is located in exon 12 (coding exon 12) of the TGM5 gene. This alteration results from a T to C substitution at nucleotide position 1922, causing the isoleucine (I) at amino acid position 641 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
