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]
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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsNov 17, 2023The c.226C>A (p.L76I) alteration is located in exon 4 (coding exon 3) of the CDK3 gene. This alteration results from a C to A substitution at nucleotide position 226, causing the leucine (L) at amino acid position 76 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
