Genes affected

CDK13 (HGNC:1733): (cyclin dependent kinase 13) The protein encoded by this gene is a member of the cyclin-dependent serine/threonine protein kinase family. Members of this family are well known for their essential roles as master switches in cell cycle control. The exact function of this protein has not yet been determined, but it may play a role in mRNA processing and may be involved in regulation of hematopoiesis. Alternatively spliced transcript variants have been described.[provided by RefSeq, Dec 2009]

The c.98C>T (p.S33F) alteration is located in exon 1 (coding exon 1) of the CDK13 gene. This alteration results from a C to T substitution at nucleotide position 98, causing the serine (S) at amino acid position 33 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
