Genes affected

PTPN14 (HGNC:9647): (protein tyrosine phosphatase non-receptor type 14) 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 noncatalytic domain similar to that of band 4.1 superfamily cytoskeleton-associated proteins, which suggested the membrane or cytoskeleton localization of this protein. It appears to regulate lymphatic development in mammals, and a loss of function mutation has been found in a kindred with a lymphedema-choanal atresia. [provided by RefSeq, Sep 2010]

This sequence change creates a premature translational stop signal (p.Arg1016*) in the PTPN14 gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in PTPN14 are known to be pathogenic (PMID: 20826270). This variant is not present in population databases (gnomAD no frequency). This variant has not been reported in the literature in individuals affected with PTPN14-related conditions. For these reasons, this variant has been classified as Pathogenic. -
