Genes affected
PTPRO (HGNC:9678): (protein tyrosine phosphatase receptor type O) This gene encodes a member of the R3 subtype family of receptor-type protein tyrosine phosphatases. These proteins are localized to the apical surface of polarized cells and may have tissue-specific functions through activation of Src family kinases. This gene contains two distinct promoters, and alternatively spliced transcript variants encoding multiple isoforms have been observed. The encoded proteins may have multiple isoform-specific and tissue-specific functions, including the regulation of osteoclast production and activity, inhibition of cell proliferation and facilitation of apoptosis. This gene is a candidate tumor suppressor, and decreased expression of this gene has been observed in several types of cancer. [provided by RefSeq, May 2011]
RERG (HGNC:15980): (RAS like estrogen regulated growth inhibitor) RERG, a member of the RAS superfamily of GTPases, inhibits cell proliferation and tumor formation (Finlin et al., 2001 [PubMed 11533059]).[supplied by OMIM, Mar 2009]

This sequence change replaces lysine, which is basic and polar, with glutamic acid, which is acidic and polar, at codon 25 of the PTPRO protein (p.Lys25Glu). This variant is present in population databases (rs531564836, gnomAD 0.07%). This variant has not been reported in the literature in individuals affected with PTPRO-related conditions. ClinVar contains an entry for this variant (Variation ID: 1922063). Algorithms developed to predict the effect of missense changes on protein structure and function output the following: SIFT: "Not Available"; PolyPhen-2: "Benign"; Align-GVGD: "Not Available". The glutamic acid amino acid residue is found in multiple mammalian species, which suggests that this missense change does not adversely affect protein function. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. -
