transglutaminase 5

Also known as: PSS2, TG(X), TGASE5, TGASEX, TGMX, TGX

NCBI Gene: 9333 ENSG00000104055 UniProt: O43548 OMIM: 603805

The encoded protein is a transglutaminase that catalyzes calcium-dependent cross-linking of proteins and contributes to cornified cell envelope formation in keratinocytes. Mutations cause peeling skin syndrome 2, an autosomal recessive disorder affecting skin integrity. The gene shows tolerance to loss-of-function variants (LOEUF 1.436), consistent with the recessive inheritance pattern.

OMIM ResearchSummary from RefSeq, OMIM, UniProt

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]

Clinical highlights

Interpreting a novel variant

Loss of function is the curated mechanism (Gene2Phenotype), though the gene is not strongly LoF-constrained in the population — weigh truncating variants against that tolerance.Curated gene-level mechanism — a prior for triage, not a per-variant call.
