RCV000792050 | SCV000931322 | uncertain significance | not provided | 2024-12-18 | criteria provided, single submitter | clinical testing | This sequence change replaces arginine, which is basic and polar, with glutamine, which is neutral and polar, at codon 19 of the NTHL1 protein (p.Arg19Gln). The frequency data for this variant in the population databases is considered unreliable, as metrics indicate poor data quality at this position in the gnomAD database. This variant has not been reported in the literature in individuals affected with NTHL1-related conditions. ClinVar contains an entry for this variant (Variation ID: 639293). 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 disruptive. Experimental studies have shown that this missense change does not substantially affect NTHL1 function (PMID: 30552997). 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. |
Ambry Genetics | RCV001024430 | SCV001186447 | uncertain significance | Hereditary cancer-predisposing syndrome | 2024-07-27 | criteria provided, single submitter | clinical testing | The c.56G>A (p.R19Q) alteration is located in exon 1 (coding exon 1) of the NTHL1 gene. This alteration results from a G to A substitution at nucleotide position 56, causing the arginine (R) at amino acid position 19 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. |
