Genes affected

CDK3 (HGNC:1772): (cyclin dependent kinase 3) This gene encodes a member of the cyclin-dependent protein kinase family. The protein promotes entry into S phase, in part by activating members of the E2F family of transcription factors. The protein also associates with cyclin C and phosphorylates the retinoblastoma 1 protein to promote exit from G0. [provided by RefSeq, Jul 2008]

CDK3 links:

TEN1-CDK3 (HGNC:44420): (TEN1-CDK3 readthrough (NMD candidate)) This locus represents naturally occurring read-through transcription between the neighboring TEN1 telomerase capping complex subunit homolog (S. cerevisiae) and cyclin-dependent kinase 3 (CDK3) genes. The read-through transcript is a candidate for nonsense-mediated mRNA decay (NMD), and is therefore unlikely to produce a protein product. [provided by RefSeq, Oct 2011]

Review Status: criteria provided, single submitter

Collection Method: clinical testing

The c.371T>C (p.I124T) alteration is located in exon 5 (coding exon 4) of the CDK3 gene. This alteration results from a T to C substitution at nucleotide position 371, causing the isoleucine (I) at amino acid position 124 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
