RCV001822688 | SCV002071891 | uncertain significance | not specified | 2021-10-01 | criteria provided, single submitter | clinical testing | DNA sequence analysis of the FANCA gene demonstrated a sequence change, c.3877G>A, in exon 39 that results in an amino acid change, p.Glu1293Lys. This sequence change does not appear to have been previously described in individuals with FANCA-related disorders and has also not been described in the population databases such as ExAC and gnomAD (dbSNP rs1015729981). The p.Glu1293Lys change affects a poorly conserved amino acid residue located in a domain of the FANCA protein that is known to be functional. The p.Glu1293Lys substitution appears to be benign using several in-silico pathogenicity prediction tools (SIFT, PolyPhen2, Align GVGD, REVEL). Due to insufficient evidences and the lack of functional studies, the clinical significance of the p.Glu1293Lys change remains unknown at this time. |

RCV002542678 | SCV002958412 | uncertain significance | Fanconi anemia | 2022-10-19 | criteria provided, single submitter | clinical testing | This sequence change replaces glutamic acid, which is acidic and polar, with lysine, which is basic and polar, at codon 1293 of the FANCA protein (p.Glu1293Lys). This variant is not present in population databases (gnomAD no frequency). This variant has not been reported in the literature in individuals affected with FANCA-related conditions. ClinVar contains an entry for this variant (Variation ID: 1338090). 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 FANCA 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. |
