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]

Feb 17, 2024

The c.2038G>A (p.A680T) alteration is located in exon 13 (coding exon 13) of the TGM5 gene. This alteration results from a G to A substitution at nucleotide position 2038, causing the alanine (A) at amino acid position 680 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
