Labcorp Genetics (formerly Invitae), Labcorp RCV001063236 SCV001228073 uncertain significance Fanconi anemia 2021-08-27 criteria provided, single submitter clinical testing This sequence change replaces glutamine with glutamic acid at codon 101 of the FANCA protein (p.Gln101Glu). The glutamine residue is moderately conserved and there is a small physicochemical difference between glutamine and glutamic acid. This variant is present in population databases (rs140412064, ExAC 0.01%). 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: 435125). Algorithms developed to predict the effect of missense changes on protein structure and function output the following: SIFT: "Tolerated"; PolyPhen-2: "Benign"; Align-GVGD: "Class C0". The glutamic acid 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.

Ambry Genetics RCV005338204 SCV005999586 uncertain significance Inborn genetic diseases 2025-01-06 criteria provided, single submitter clinical testing The p.Q101E variant (also known as c.301C>G), located in coding exon 4 of the FANCA gene, results from a C to G substitution at nucleotide position 301. The glutamine at codon 101 is replaced by glutamic acid, 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.
