Labcorp Genetics (formerly Invitae), Labcorp RCV001347436 SCV001541696 uncertain significance Fanconi anemia 2024-12-09 criteria provided, single submitter clinical testing This sequence change replaces isoleucine, which is neutral and non-polar, with valine, which is neutral and non-polar, at codon 608 of the FANCM protein (p.Ile608Val). This variant is present in population databases (rs761833981, gnomAD 0.004%). This variant has not been reported in the literature in individuals affected with FANCM-related conditions. ClinVar contains an entry for this variant (Variation ID: 1043345). An algorithm developed to predict the effect of missense changes on protein structure and function outputs the following: PolyPhen-2: "Benign". The valine amino acid residue is found in multiple mammalian species, which suggests that this missense change does not adversely affect 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.
GeneDx RCV001786478 SCV002028548 uncertain significance not provided 2024-06-05 criteria provided, single submitter clinical testing Not observed at significant frequency in large population cohorts (gnomAD); In silico analysis indicates that this missense variant does not alter protein structure/function; Has not been previously published as pathogenic or benign to our knowledge
Ambry Genetics RCV004978384 SCV005582877 uncertain significance Inborn genetic diseases 2024-11-21 criteria provided, single submitter clinical testing The p.I608V variant (also known as c.1822A>G), located in coding exon 11 of the FANCM gene, results from an A to G substitution at nucleotide position 1822. The isoleucine at codon 608 is replaced by valine, an amino acid with highly similar properties. This amino acid position is conserved. In addition, this alteration is predicted to be tolerated by in silico analysis. Based on the available evidence, the clinical significance of this variant remains unclear.
