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]

The c.497T>C (p.M166T) alteration is located in exon 3 (coding exon 3) of the PTPRO gene. This alteration results from a T to C substitution at nucleotide position 497, causing the methionine (M) at amino acid position 166 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -

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. Algorithms developed to predict the effect of missense changes on protein structure and function (SIFT, PolyPhen-2, Align-GVGD) all suggest that this variant is likely to be disruptive. This variant has not been reported in the literature in individuals affected with PTPRO-related conditions. This variant is present in population databases (rs376857700, gnomAD 0.009%). This sequence change replaces methionine, which is neutral and non-polar, with threonine, which is neutral and polar, at codon 166 of the PTPRO protein (p.Met166Thr). -
