Genes affected

CDK5RAP1 (HGNC:15880): (CDK5 regulatory subunit associated protein 1) This gene encodes a regulator of cyclin-dependent kinase 5 activity. This protein has also been reported to modify RNA by adding a methylthio-group and may thus have a dual function as an RNA methylthiotransferase and as an inhibitor of cyclin-dependent kinase 5 activity. Alternative splicing results in multiple transcript variants that encode different isoforms. [provided by RefSeq, May 2013]

The c.1037A>G (p.Q346R) alteration is located in exon 8 (coding exon 7) of the CDK5RAP1 gene. This alteration results from a A to G substitution at nucleotide position 1037, causing the glutamine (Q) at amino acid position 346 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
