Genes affected

KIAA0586 (HGNC:19960): (KIAA0586) This gene encodes a conserved centrosomal protein that functions in ciliogenesis and responds to hedgehog signaling. Mutations in this gene causes Joubert syndrome 23. Alternative splicing results in multiple transcript variants and protein isoforms. [provided by RefSeq, Aug 2016]

The c.1080G>C (p.R360S) alteration is located in exon 8 (coding exon 8) of the KIAA0586 gene. This alteration results from a G to C substitution at nucleotide position 1080, causing the arginine (R) at amino acid position 360 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -

The R413S variant in the KIAA0586 gene has not been reported previously as a pathogenic variant, nor as a benign variant, to our knowledge. The R413S variant is not observed in the homozygous state or at a significant frequency in large population cohorts (Lek et al., 2016; 1000 Genomes Consortium et al., 2015; Exome Variant Server). The R413S variant is a semi-conservative amino acid substitution, which may impact secondary protein structure as these residues differ in some properties. This substitution occurs at a position that is not conserved and in silico analysis is inconsistent in its predictions as to whether or not the variant is damaging to the protein structure/function. We interpret R413S as a variant of uncertain significance. -

This sequence change replaces arginine, which is basic and polar, with serine, which is neutral and polar, at codon 413 of the KIAA0586 protein (p.Arg413Ser). This variant is present in population databases (rs200094677, gnomAD 0.01%). This variant has not been reported in the literature in individuals affected with KIAA0586-related conditions. ClinVar contains an entry for this variant (Variation ID: 432994). Algorithms developed to predict the effect of missense changes on protein structure and function output the following: SIFT: "Tolerated"; PolyPhen-2: "Possibly Damaging"; Align-GVGD: "Class C0". The serine amino acid residue is found in multiple mammalian species, which suggests that this missense change does not adversely affect protein function. 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. -
