Invitae RCV001361952 SCV001557947 uncertain significance Mucopolysaccharidosis, MPS-III-B; Charcot-Marie-Tooth disease, axonal type 2V 2020-05-21 criteria provided, single submitter clinical testing This sequence change replaces valine with methionine at codon 501 of the NAGLU protein (p.Val501Met). The valine residue is highly conserved and there is a small physicochemical difference between valine and methionine. This variant is not present in population databases (ExAC no frequency). This variant has not been reported in the literature in individuals with NAGLU-related conditions. Algorithms developed to predict the effect of missense changes on protein structure and function are either unavailable or do not agree on the potential impact of this missense change (SIFT: Deleterious; PolyPhen-2: Probably Damaging; Align-GVGD: Class C0). 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.
