Labcorp Genetics (formerly Invitae), Labcorp RCV003104727 SCV003783083 uncertain significance not provided 2023-09-15 criteria provided, single submitter clinical testing In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. An algorithm developed to predict the effect of missense changes on protein structure and function (PolyPhen-2) suggests that this variant is likely to be tolerated. ClinVar contains an entry for this variant (Variation ID: 2415515). This variant has not been reported in the literature in individuals affected with NTHL1-related conditions. This variant is not present in population databases (gnomAD no frequency). This sequence change replaces proline, which is neutral and non-polar, with threonine, which is neutral and polar, at codon 36 of the NTHL1 protein (p.Pro36Thr).
Ambry Genetics RCV003162124 SCV003877359 uncertain significance Hereditary cancer-predisposing syndrome 2022-12-17 criteria provided, single submitter clinical testing The p.P36T variant (also known as c.106C>A), located in coding exon 1 of the NTHL1 gene, results from a C to A substitution at nucleotide position 106. The proline at codon 36 is replaced by threonine, an amino acid with highly similar properties. This amino acid position is conserved. In addition, this alteration is predicted to be tolerated by in silico analysis. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear.
