Genes affected

CEP89 (HGNC:25907): (centrosomal protein 89) Involved in non-motile cilium assembly. Acts upstream of or within cilium assembly. Located in several cellular components, including cytosol; microtubule cytoskeleton; and non-motile cilium. Part of ciliary transition fiber. [provided by Alliance of Genome Resources, Apr 2022]

Feb 08, 2022

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 (SIFT, PolyPhen-2, Align-GVGD) all suggest that this variant is likely to be tolerated. This sequence change replaces alanine, which is neutral and non-polar, with aspartic acid, which is acidic and polar, at codon 780 of the CEP89 protein (p.Ala780Asp). This variant is present in population databases (no rsID available, gnomAD 0.0009%). This variant has not been reported in the literature in individuals affected with CEP89-related conditions. -
