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.740C>T (p.A247V) alteration is located in exon 6 (coding exon 5) of the CDK5RAP1 gene. This alteration results from a C to T substitution at nucleotide position 740, causing the alanine (A) at amino acid position 247 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
