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]

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. 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 disruptive. ClinVar contains an entry for this variant (Variation ID: 1374897). This variant has not been reported in the literature in individuals affected with CEP135-related conditions. This variant is present in population databases (rs753628355, gnomAD 0.02%). This sequence change replaces alanine, which is neutral and non-polar, with valine, which is neutral and non-polar, at codon 57 of the CEP135 protein (p.Ala57Val). -
