RCV000387476 | SCV000356724 | uncertain significance | Fumarase deficiency | 2018-01-12 | criteria provided, single submitter | clinical testing | This variant was observed in the ICSL laboratory as part of a predisposition screen in an ostensibly healthy population. It had not been previously curated by ICSL or reported in the Human Gene Mutation Database (HGMD: prior to June 1st, 2018), and was therefore a candidate for classification through an automated scoring system. Utilizing variant allele frequency, disease prevalence and penetrance estimates, and inheritance mode, an automated score was calculated to assess if this variant is too frequent to cause the disease. Based on the score, this variant could not be ruled out of causing disease and therefore its association with disease required further investigation. A literature search was performed for the gene, cDNA change, and amino acid change (if applicable). No publications were found based on this search. This variant was therefore classified as a variant of unknown significance for this disease. |

Ambry Genetics | RCV000570874 | SCV000673380 | uncertain significance | Hereditary cancer-predisposing syndrome | 2023-05-20 | criteria provided, single submitter | clinical testing | The p.N64D variant (also known as c.190A>G), located in coding exon 2 of the FH gene, results from an A to G substitution at nucleotide position 190. The asparagine at codon 64 is replaced by aspartic acid, an amino acid with highly similar properties. This amino acid position is not well conserved in available vertebrate species. 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. |
Invitae | RCV002520481 | SCV000756717 | uncertain significance | not provided | 2022-09-23 | criteria provided, single submitter | clinical testing | This sequence change replaces asparagine, which is neutral and polar, with aspartic acid, which is acidic and polar, at codon 64 of the FH protein (p.Asn64Asp). This variant is present in population databases (no rsID available, gnomAD 0.006%). This variant has not been reported in the literature in individuals affected with FH-related conditions. ClinVar contains an entry for this variant (Variation ID: 296875). Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae indicates that this missense variant is not expected to disrupt FH protein function. 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. |
