Genes affected

CDK5RAP2 (HGNC:18672): (CDK5 regulatory subunit associated protein 2) This gene encodes a regulator of CDK5 (cyclin-dependent kinase 5) activity. The protein encoded by this gene is localized to the centrosome and Golgi complex, interacts with CDK5R1 and pericentrin (PCNT), plays a role in centriole engagement and microtubule nucleation, and has been linked to primary microcephaly and Alzheimer's disease. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Jan 2013]

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 output the following: SIFT: "Deleterious"; PolyPhen-2: "Benign"; Align-GVGD: "Class C15". The valine amino acid residue is found in multiple mammalian species, which suggests that this missense change does not adversely affect protein function. ClinVar contains an entry for this variant (Variation ID: 158150). This variant has not been reported in the literature in individuals affected with CDK5RAP2-related conditions. This variant is present in population databases (rs201864352, gnomAD 0.03%). This sequence change replaces methionine, which is neutral and non-polar, with valine, which is neutral and non-polar, at codon 1465 of the CDK5RAP2 protein (p.Met1465Val). -
