Genes affected

PTPN9 (HGNC:9661): (protein tyrosine phosphatase non-receptor type 9) 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 contains an N-terminal domain that shares a significant similarity with yeast SEC14, which is a protein that has phosphatidylinositol transfer activity and is required for protein secretion through the Golgi complex in yeast. This PTP was found to be activated by polyphosphoinositide, and is thought to be involved in signaling events regulating phagocytosis. [provided by RefSeq, Jul 2008]

The c.1265C>T (p.S422F) alteration is located in exon 11 (coding exon 11) of the PTPN9 gene. This alteration results from a C to T substitution at nucleotide position 1265, causing the serine (S) at amino acid position 422 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
