Epileptic encephalopathy Uncertain:1
Uncertain significance, criteria provided, single submitter | clinical testing | Invitae | Aug 12, 2021 | This sequence change replaces glutamine with arginine at codon 2188 of the FASN protein (p.Gln2188Arg). The glutamine residue is moderately conserved and there is a small physicochemical difference between glutamine and arginine. This variant is not present in population databases (ExAC no frequency). This variant has not been reported in the literature in individuals affected with FASN-related conditions. ClinVar contains an entry for this variant (Variation ID: 581409). Algorithms developed to predict the effect of missense changes on protein structure and function (SIFT, PolyPhen-2, Align-GVGD) all suggest that this variant is likely to be tolerated. 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. - |
