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]

The c.3500T>C (p.I1167T) alteration is located in exon 19 (coding exon 18) of the PTPN14 gene. This alteration results from a T to C substitution at nucleotide position 3500, causing the isoleucine (I) at amino acid position 1167 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -

The PTPN14 c.3500T>C (p.Ile1167Thr) variant was identified at a near-heterozygous allelic fraction. This variant, to our knowledge, has not been reported in the medical literature. This variant has been reported in the ClinVar database as a germline variant of uncertain significance by one submitter (ClinVar ID: 2359362). Computational predictors suggest that the variant does not impact the PTPN14 function. Due to limited information and based on ACMG/AMP guidelines for variant interpretation (Richards S et al., PMID: 25741868), the clinical significance of this variant is uncertain at this time. -
