Description

This sequence change replaces valine, which is neutral and non-polar, with isoleucine, which is neutral and non-polar, at codon 900 of the LAMA4 protein (p.Val900Ile). This variant is present in population databases (rs138030555, gnomAD 0.03%). This variant has not been reported in the literature in individuals affected with LAMA4-related conditions. ClinVar contains an entry for this variant (Variation ID: 626729). 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 isoleucine 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.
