not provided Uncertain:1
In silico analysis, which includes protein predictors and evolutionary conservation, supports that this variant does not alter protein structure/function; Has not been previously published as pathogenic or benign to our knowledge -
Nemaline myopathy 9 Uncertain:1
This sequence change replaces arginine, which is basic and polar, with glutamine, which is neutral and polar, at codon 205 of the KLHL41 protein (p.Arg205Gln). This variant is present in population databases (rs576773055, gnomAD 0.02%). This variant has not been reported in the literature in individuals affected with KLHL41-related conditions. ClinVar contains an entry for this variant (Variation ID: 474873). Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae indicates that this missense variant is not expected to disrupt KLHL41 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. -
