Description

The PTPN14 c.2216C>T (p.Ala739Val) variant was identified at a near heterozygous allele fraction of 49%, a frequency which may be consistent with it being of germline origin. This variant, to our knowledge, has not been reported in the medical literature. This variant is only observed on 38/1,613,146 alleles in the general population (gnomAD v4.0.0), indicating it is not a common variant. Computational predictors are uncertain as to the impact of this variant on 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 the PTPN14 c.2216C>T (p.Ala739Val) variant is uncertain at this time.
