RCV001367718 | SCV001564078 | uncertain significance | Neuronal ceroid lipofuscinosis 7 | 2020-05-21 | criteria provided, single submitter | clinical testing | 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 are either unavailable or do not agree on the potential impact of this missense change (SIFT: "Deleterious"; PolyPhen-2: "Possibly Damaging"; Align-GVGD: "Class C0"). This variant has not been reported in the literature in individuals with MFSD8-related conditions. The frequency data for this variant in the population databases is considered unreliable, as metrics indicate poor data quality at this position in the ExAC database. This sequence change replaces leucine with isoleucine at codon 467 of the MFSD8 protein (p.Leu467Ile). The leucine residue is highly conserved and there is a small physicochemical difference between leucine and isoleucine. |
