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.2190G>T (p.Q730H) alteration is located in exon 22 (coding exon 21) of the PTPN3 gene. This alteration results from a G to T substitution at nucleotide position 2190, causing the glutamine (Q) at amino acid position 730 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
