Familial acute necrotizing encephalopathy Uncertain:1
Uncertain significance, criteria provided, single submitter | clinical testing | Invitae | Jun 14, 2017 | This sequence change replaces asparagine with aspartic acid at codon 728 of the RANBP2 protein (p.Asn728Asp). The asparagine residue is highly conserved and there is a small physicochemical difference between asparagine and aspartic acid. 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 variant 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 aspartic acid 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 and their clinical significance is uncertain. In summary, this variant has uncertain impact on RANBP2 function. The available evidence is currently insufficient to determine its role in disease. Therefore, it has been classified as a Variant of Uncertain Significance. - |
