Genes affected

PTPRC (HGNC:9666): (protein tyrosine phosphatase receptor type C) The protein encoded by this gene is a member of the protein tyrosine phosphatase (PTP) family. PTPs are known to be signaling molecules that regulate a variety of cellular processes including cell growth, differentiation, mitosis, and oncogenic transformation. This PTP contains an extracellular domain, a single transmembrane segment and two tandem intracytoplasmic catalytic domains, and thus is classified as a receptor type PTP. This PTP has been shown to be an essential regulator of T- and B-cell antigen receptor signaling. It functions through either direct interaction with components of the antigen receptor complexes, or by activating various Src family kinases required for the antigen receptor signaling. This PTP also suppresses JAK kinases, and thus functions as a regulator of cytokine receptor signaling. Alternatively spliced transcripts variants of this gene, which encode distinct isoforms, have been reported. [provided by RefSeq, Jun 2012]

The c.694A>G (p.N232D) alteration is located in exon 9 (coding exon 8) of the PTPRC gene. This alteration results from a A to G substitution at nucleotide position 694, causing the asparagine (N) at amino acid position 232 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear.

This sequence change replaces asparagine, which is neutral and polar, with aspartic acid, which is acidic and polar, at codon 234 of the PTPRC protein (p.Asn234Asp). This variant is present in population databases (rs535416574, gnomAD 0.05%). This variant has not been reported in the literature in individuals affected with PTPRC-related conditions. ClinVar contains an entry for this variant (Variation ID: 577072). Algorithms developed to predict the effect of missense changes on protein structure and function output the following: SIFT: "Tolerated"; PolyPhen-2: "Benign"; Align-GVGD: "Class C0". The aspartic 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.
