Genes affected

PSTPIP1 (HGNC:9580): (proline-serine-threonine phosphatase interacting protein 1) This gene encodes a cytoskeletal protein that is highly expressed in hemopoietic tissues. This protein functions via its interaction with several different proteins involved in cytoskeletal organization and inflammatory processes. It binds to the cytoplasmic tail of CD2, an effector of T cell activation and adhesion, downregulating CD2-triggered adhesion. It binds PEST-type protein tyrosine phosphatases (PTP) and directs them to c-Abl kinase to mediate c-Abl dephosphorylation, thereby, regulating c-Abl activity. It also interacts with pyrin, which is found in association with the cytoskeleton in myeloid/monocytic cells and modulates immunoregulatory functions. Mutations in this gene are associated with PAPA (pyogenic sterile arthritis, pyoderma gangrenosum, and acne) syndrome. It is hypothesized that the disease-causing mutations compromise physiologic signaling necessary for the maintenance of a proper inflammatory response. [provided by RefSeq, Mar 2016]

The PSTPIP1 c.1207G>C; p.Gly403Arg variant (rs369113632) has been published in the literature in an individual with pyoderma gangrenosum (Zeeli 2015). The variant is reported in the ClinVar database (Variation ID: 440207) and in the general population with an overall allele frequency of 0.03% (77/246,962 alleles, including 1 homozygote) in the Genome Aggregation Database. The glycine at codon 403 is moderately conserved, and computational analyses predict that this variant is deleterious (REVEL: 0.715). Due to limited information, the clinical significance of the p.Gly403Arg variant is uncertain at this time. References: Zeeli T et al. Pyoderma gangrenosum, acne and ulcerative colitis in a patient with a novel mutation in the PSTPIP1 gene. Clin Exp Dermatol. 2015 40(4):367-72. PMID: 25683018. -
