Invitae RCV000197177 SCV000254249 uncertain significance Fanconi anemia 2022-10-04 criteria provided, single submitter clinical testing This sequence change replaces leucine, which is neutral and non-polar, with phenylalanine, which is neutral and non-polar, at codon 337 of the FANCC protein (p.Leu337Phe). This variant is present in population databases (rs587779899, gnomAD 0.0009%). This variant has not been reported in the literature in individuals affected with FANCC-related conditions. ClinVar contains an entry for this variant (Variation ID: 127530). 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 FANCC 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.
Ambry Genetics RCV002433605 SCV002744845 uncertain significance Hereditary cancer-predisposing syndrome 2021-09-07 criteria provided, single submitter clinical testing The p.L337F variant (also known as c.1009C>T), located in coding exon 10 of the FANCC gene, results from a C to T substitution at nucleotide position 1009. The leucine at codon 337 is replaced by phenylalanine, 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. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear.
