Invitae | RCV000798437 | SCV000938054 | uncertain significance | Muscular dystrophy-dystroglycanopathy (congenital with brain and eye anomalies), type a, 11 | 2022-07-19 | criteria provided, single submitter | clinical testing | This variant has not been reported in the literature in individuals affected with B3GALNT2-related conditions. This variant is present in population databases (rs779469431, gnomAD 0.01%). This sequence change replaces phenylalanine, which is neutral and non-polar, with isoleucine, which is neutral and non-polar, at codon 264 of the B3GALNT2 protein (p.Phe264Ile). ClinVar contains an entry for this variant (Variation ID: 644502). 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. Algorithms developed to predict the effect of missense changes on protein structure and function (SIFT, PolyPhen-2, Align-GVGD) all suggest that this variant is likely to be tolerated. |
