Labcorp Genetics (formerly Invitae), Labcorp RCV000814108 SCV000954507 uncertain significance Deficiency of alpha-mannosidase 2021-09-01 criteria provided, single submitter clinical testing This sequence change replaces valine with glutamic acid at codon 75 of the MAN2B1 protein (p.Val75Glu). The valine residue is highly conserved and there is a moderate physicochemical difference between valine and glutamic acid. This variant is not present in population databases (ExAC no frequency). This variant has not been reported in the literature in individuals affected with MAN2B1-related conditions. 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 disruptive. 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.
