Genes affected

CEP135 (HGNC:29086): (centrosomal protein 135) This gene encodes a centrosomal protein, which acts as a scaffolding protein during early centriole biogenesis, and is also required for centriole-centriole cohesion during interphase. Mutations in this gene are associated with autosomal recessive primary microcephaly-8. [provided by RefSeq, Jun 2012]

This sequence change replaces glutamine, which is neutral and polar, with lysine, which is basic and polar, at codon 98 of the CEP135 protein (p.Gln98Lys). This variant is present in population databases (rs749547226, gnomAD 0.01%). This variant has not been reported in the literature in individuals affected with CEP135-related conditions. Algorithms developed to predict the effect of missense changes on protein structure and function output the following: SIFT: "Tolerated"; PolyPhen-2: "Benign"; Align-GVGD: "Class C0". The lysine 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. -
