Labcorp Genetics (formerly Invitae), Labcorp RCV002582481 SCV003493587 uncertain significance Fanconi anemia 2022-03-05 criteria provided, single submitter clinical testing This sequence change replaces proline, which is neutral and non-polar, with serine, which is neutral and polar, at codon 259 of the FANCA protein (p.Pro259Ser). This variant is present in population databases (rs200988394, gnomAD 0.008%). This variant has not been reported in the literature in individuals affected with FANCA-related conditions. 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.
PreventionGenetics, part of Exact Sciences RCV003404094 SCV004105899 uncertain significance FANCA-related disorder 2022-11-29 criteria provided, single submitter clinical testing The FANCA c.775C>T variant is predicted to result in the amino acid substitution p.Pro259Ser. To our knowledge, this variant has not been reported in the literature. This variant is reported in 0.0080% of alleles in individuals of African descent in gnomAD (http://gnomad.broadinstitute.org/variant/16-89869684-G-A). At this time, the clinical significance of this variant is uncertain due to the absence of conclusive functional and genetic evidence.
