Genes affected

PTPRJ (HGNC:9673): (protein tyrosine phosphatase receptor type J) 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, mitotic cycle, and oncogenic transformation. This PTP possesses an extracellular region containing five fibronectin type III repeats, a single transmembrane region, and a single intracytoplasmic catalytic domain, and thus represents a receptor-type PTP. This protein is present in all hematopoietic lineages, and was shown to negatively regulate T cell receptor signaling possibly through interfering with the phosphorylation of Phospholipase C Gamma 1 and Linker for Activation of T Cells. This protein can also dephosphorylate the PDGF beta receptor, and may be involved in UV-induced signal transduction. Multiple transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Jul 2008]

The PTPRJ c.83_85dupTGC variant is predicted to result in an in-frame duplication (p.Leu28dup). To our knowledge, this variant has not been reported in the literature. This variant is reported in 0.024% of alleles in individuals of African descent in gnomAD (http://gnomad.broadinstitute.org/variant/11-48002529-C-CGCT). At this time, the clinical significance of this variant is uncertain due to the absence of conclusive functional and genetic evidence. -
