This sequence change replaces arginine, which is basic and polar, with histidine, which is basic and polar, at codon 199 of the FCHO1 protein (p.Arg199His). This variant is present in population databases (rs767365658, gnomAD 0.007%). This variant has not been reported in the literature in individuals affected with FCHO1-related conditions. ClinVar contains an entry for this variant (Variation ID: 2077811). Algorithms developed to predict the effect of missense changes on protein structure and function output the following: SIFT: "Not Available"; PolyPhen-2: "Benign"; Align-GVGD: "Not Available". The histidine amino acid residue is found in multiple mammalian species, which suggests that this missense change does not adversely affect protein function. 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.

This sequence change replaces arginine, which is basic and polar, with histidine, which is basic and polar, at codon 199 of the FCHO1 protein (p.Arg199His). This variant is present in population databases (rs767365658, gnomAD 0.007%). This variant has not been reported in the literature in individuals affected with FCHO1-related conditions. ClinVar contains an entry for this variant (Variation ID: 2077811). Algorithms developed to predict the effect of missense changes on protein structure and function output the following: SIFT: "Not Available"; PolyPhen-2: "Benign"; Align-GVGD: "Not Available". The histidine amino acid residue is found in multiple mammalian species, which suggests that this missense change does not adversely affect protein function. 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. (less)

HelpRecord last updated Sep 29, 2024
This date represents the last time this VCV record was updated. The update may be due to an update to one of the included submitted records (SCVs), or due to an update that ClinVar made to the variant such as adding HGVS expressions or a rs number. So this date may be different from the date of the “most recent submission” reported at the top of this page.
