Invitae | RCV000698107 | SCV000826750 | uncertain significance | Epileptic encephalopathy | 2018-03-01 | criteria provided, single submitter | clinical testing | This sequence change replaces glycine with aspartic acid at codon 1692 of the FASN protein (p.Gly1692Asp). The glycine residue is moderately conserved and there is a moderate physicochemical difference between glycine and aspartic acid. While this variant is not present in population databases, the frequency information is 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 FASN-related disease. Algorithms developed to predict the effect of missense changes on protein structure and function do not agree on the potential impact of this missense change (SIFT: "Tolerated"; PolyPhen-2: "Possibly 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. |
