Invitae | RCV001236905 | SCV001409646 | uncertain significance | Primary open angle glaucoma; Amyotrophic lateral sclerosis type 12; Glaucoma 1, open angle, E | 2022-07-06 | criteria provided, single submitter | clinical testing | This variant is present in population databases (rs760339006, gnomAD 0.004%). This sequence change replaces valine, which is neutral and non-polar, with leucine, which is neutral and non-polar, at codon 252 of the OPTN protein (p.Val252Leu). This variant has not been reported in the literature in individuals affected with OPTN-related conditions. 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. Algorithms developed to predict the effect of missense changes on protein structure and function output the following: SIFT: "Tolerated"; PolyPhen-2: "Benign"; Align-GVGD: "Class C0". The leucine amino acid residue is found in multiple mammalian species, which suggests that this missense change does not adversely affect protein function. ClinVar contains an entry for this variant (Variation ID: 962957). |
