Genes affected

CDK5RAP3 (HGNC:18673): (CDK5 regulatory subunit associated protein 3) This gene encodes a protein that has been reported to function in signaling pathways governing transcriptional regulation and cell cycle progression. It may play a role in tumorigenesis and metastasis. A pseudogene of this gene is located on the long arm of chromosome 20. Alternative splicing results in multiple transcript variants that encode different isoforms. [provided by RefSeq, May 2013]

The c.145C>A (p.P49T) alteration is located in exon 3 (coding exon 3) of the CDK5RAP3 gene. This alteration results from a C to A substitution at nucleotide position 145, causing the proline (P) at amino acid position 49 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
