Labcorp Genetics (formerly Invitae), Labcorp RCV000554948 SCV000646825 uncertain significance Familial acute necrotizing encephalopathy 2017-04-06 criteria provided, single submitter clinical testing In summary, this variant is a novel missense change that is not predicted to affect protein function. There is no indication that it causes disease, but the available evidence is currently insufficient to prove that conclusively. Therefore, it has been classified as a Variant of Uncertain Significance. This sequence change replaces threonine with alanine at codon 1885 of the RANBP2 protein (p.Thr1885Ala). The threonine residue is moderately conserved and there is a small physicochemical difference between threonine and alanine. This variant is not present in population databases (ExAC no frequency) and has not been reported in the literature in individuals with a RANBP2-related disease. Algorithms developed to predict the effect of missense changes on protein structure and function output the following: SIFT: "Tolerated"; PolyPhen-2: "Benign"; Align-GVGD: "Class C0". The alanine amino acid residue is found in multiple mammalian species, suggesting that this missense change does not adversely affect protein function. These predictions have not been confirmed by published functional studies.
