Genes affected
CEP41 (HGNC:12370): (centrosomal protein 41) This gene encodes a centrosomal and microtubule-binding protein which is predicted to have two coiled-coil domains and a rhodanese domain. In human retinal pigment epithelial cells the protein localized to centrioles and cilia. Mutations in this gene have been associated with Joubert Syndrome 15; an autosomal recessive ciliopathy and neurological disorder. Alternative splicing results in multiple transcript variants.

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 disruptive. ClinVar contains an entry for this variant (Variation ID: 30841). This missense change has been observed in individual(s) with clinical features of Joubert syndrome (PMID: 22246503). This variant is present in population databases (rs140259402, gnomAD 0.003%). This sequence change replaces arginine, which is basic and polar, with histidine, which is basic and polar, at codon 179 of the CEP41 protein (p.Arg179His). -
