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]

Submissions by phenotype

not provided Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingInvitaeJan 02, 2024This sequence change replaces glycine, which is neutral and non-polar, with serine, which is neutral and polar, at codon 768 of the CEP89 protein (p.Gly768Ser). 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. An algorithm developed to predict the effect of missense changes on protein structure and function (PolyPhen-2) suggests 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. -
