Genes affected

PTPN3 (HGNC:9655): (protein tyrosine phosphatase non-receptor type 3) 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 protein contains a C-terminal PTP domain and an N-terminal domain homologous to the band 4.1 superfamily of cytoskeletal-associated proteins. P97, a cell cycle regulator involved in a variety of membrane related functions, has been shown to be a substrate of this PTP. This PTP was also found to interact with, and be regulated by adaptor protein 14-3-3 beta. Several alternatively spliced transcript variants encoding different isoforms have been found for this gene.

The c.2476A>T (p.N826Y) alteration is located in exon 24 (coding exon 23) of the PTPN3 gene. This alteration results from a A to T substitution at nucleotide position 2476, causing the asparagine (N) at amino acid position 826 to be replaced by a tyrosine (Y). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
