Invitae | RCV001066284 | SCV001231291 | uncertain significance | Leber congenital amaurosis 4 | 2021-08-27 | criteria provided, single submitter | clinical testing | This sequence change replaces valine with alanine at codon 249 of the AIPL1 protein (p.Val249Ala). The valine residue is highly conserved and there is a small physicochemical difference between valine and alanine. This variant is present in population databases (rs760491360, ExAC 0.02%). This variant has not been reported in the literature in individuals affected with AIPL1-related conditions. 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. |
