Description

Not observed at significant frequency in large population cohorts (gnomAD); In silico analysis supports that this missense variant has a deleterious effect on protein structure/function; Also known as FH c.968G>A, p.Ser323Asn; This variant is associated with the following publications: (PMID: 15937070, 12761039, 31299266, 18366737, 21630274, 12772087, 16597677, 16029320, 16237213, 30761759, 22561013, 35022142, 31831373, 21445611)

Description

This sequence change replaces serine, which is neutral and polar, with asparagine, which is neutral and polar, at codon 366 of the FH protein (p.Ser366Asn). This variant is not present in population databases (gnomAD no frequency). This missense change has been observed in individuals with multiple cutaneous and uterine leiomyomatosis (MCUL) or hereditary leiomyomatosis and renal cell cancer (HLRCC) (PMID: 12761039, 12772087, 16237213; Invitae). This variant is also known as G968A or S323N. ClinVar contains an entry for this variant (Variation ID: 214419). 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 expected to disrupt FH protein function with a positive predictive value of 95%. For these reasons, this variant has been classified as Pathogenic.

Description

The FH c.1097G>A (p.Ser366Asn) variant has been reported in the published literature in individuals with phenotypes associated with hereditary leiomyomatosis and renal cell cancer (HLRCC)(PMID: 12772087 (2003), 16237213 (2005), 21630274 (2011), 31299266 (2019)). Immunohistochemical analysis of tumors from patients with this variant showed loss of heterozygosity and were positive for (2-succinyl) cysteine (2SC) (termed protein succination) due to deficient fumarase (PMID: 21630274 (2011)). Additionally, this variant is predicted to alter the active site of the FH protein (PMID: 21445611 (2011), 12761039 (2003)). This variant has not been reported in large, multi-ethnic general populations (Genome Aggregation Database, http://gnomad.broadinstitute.org). Analysis of this variant using bioinformatics tools for the prediction of the effect of amino acid changes on protein structure and function yielded predictions that this variant is damaging. Based on the available information, this variant is classified as pathogenic.
