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 p.Glu523Val variant (rs116464756) has not been reported in the medical literature, gene specific variation databases, nor has it been previously identified by our laboratory. This variant is listed in the genome Aggregation Database (gnomAD) with an African population frequency of 0.8 percent (identified on 193 out of 24,032 chromosomes).The glutamic acid at position 523 is weakly conserved (Alamut v.2.9.0) but computational analyses of the effects of the p.Glu523Val variant on protein structure and function provide conflicting results (SIFT: damaging, MutationTaster: polymorphism, PolyPhen-2: benign). Altogether, there is not enough evidence to classify the p.Glu523Val variant with certainty. -

PTPRC NM_002838.4 exon 14 p.Glu523Val (c.1568A>T): This variant has not been reported in the literature and is present in 0.8% (203/24962) of African alleles in the Genome Aggregation Database (http://gnomad.broadinstitute.org/variant/1-198687340-A-T). This variant is present in ClinVar (Variation ID:506974). Evolutionary conservation and computational predictive tools suggest that this variant may not impact the protein. In summary, data on this variant is insufficient for disease classification. Therefore, the clinical significance of this variant is uncertain. -
