RCV000824410 | SCV000965308 | uncertain significance | Familial cancer of breast | 2023-09-08 | 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 disruptive. ClinVar contains an entry for this variant (Variation ID: 666010). This variant has not been reported in the literature in individuals affected with BARD1-related conditions. This variant is present in population databases (no rsID available, gnomAD 0.003%). This sequence change replaces asparagine, which is neutral and polar, with histidine, which is basic and polar, at codon 98 of the BARD1 protein (p.Asn98His). |
Ambry Genetics | RCV001017521 | SCV001178611 | uncertain significance | Hereditary cancer-predisposing syndrome | 2023-05-04 | criteria provided, single submitter | clinical testing | The p.N98H variant (also known as c.292A>C), located in coding exon 3 of the BARD1 gene, results from an A to C substitution at nucleotide position 292. The asparagine at codon 98 is replaced by histidine, an amino acid with similar properties. This amino acid position is highly conserved in available vertebrate species. In addition, the in silico prediction for this alteration is inconclusive. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear. |

RCV001017521 | SCV001341674 | uncertain significance | Hereditary cancer-predisposing syndrome | 2023-12-04 | criteria provided, single submitter | clinical testing | This missense variant replaces asparagine with histidine at codon 98 of the BARD1 protein. Computational prediction is inconclusive regarding the impact of this variant on protein structure and function (internally defined REVEL score threshold 0.5 < inconclusive < 0.7, PMID: 27666373). To our knowledge, functional studies have not been reported for this variant. This variant has not been reported in individuals affected with BARD1-related disorders in the literature. This variant has been identified in 1/251182 chromosomes in the general population by the Genome Aggregation Database (gnomAD). The available evidence is insufficient to determine the role of this variant in disease conclusively. Therefore, this variant is classified as a Variant of Uncertain Significance. |
