Ambry Genetics | RCV000571864 | SCV000664707 | likely pathogenic | Hereditary cancer-predisposing syndrome | 2024-10-17 | criteria provided, single submitter | clinical testing | The p.H94R variant (also known as c.281A>G), located in coding exon 5 of the BAP1 gene, results from an A to G substitution at nucleotide position 281. The histidine at codon 94 is replaced by arginine, an amino acid with highly similar properties. This variant was identified in multiple individuals with a personal and/or family history of BAP1-associated disease (Ambry internal data; Walpole S et al. J Natl Cancer Inst, 2018 Dec;110:1328-1341; Repo P et al. Hum Mol Genet, 2019 Jul;28:2415-2426; Helgadottir H et al. Acta Oncol, 2023 Jun;62:565-570). This alteration was non-functional in a high throughput genome editing haploid cell survival assay (Waters AJ et al. Nat Genet, 2024 Jul;56:1434-1445). This amino acid position is highly conserved in available vertebrate species. In addition, this alteration is predicted to be deleterious by in silico analysis. Based on the majority of available evidence to date, this variant is likely to be pathogenic. |

RCV001214123 | SCV001385789 | uncertain significance | BAP1-related tumor predisposition syndrome | 2019-08-08 | 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. This sequence change replaces histidine with arginine at codon 94 of the BAP1 protein (p.His94Arg). The histidine residue is highly conserved and there is a small physicochemical difference between histidine and arginine. This variant is not present in population databases (ExAC no frequency). This variant has been observed in an individual affected with uveal melanoma (PMID: 30517737). ClinVar contains an entry for this variant (Variation ID: 480852). This variant has been reported to affect BAP1 protein function (PMID: 31058963). |
