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]

ACMG classification

Verdict is Likely_pathogenic. Variant got 9 ACMG points.

• PM1: In a domain Protein kinase (size 293) in uniprot entity CDK13_HUMAN there are 6 pathogenic changes around while only 0 benign (100%) in NM_003718.5
• PM2: Very rare variant in population databases, with high coverage
• PP3: MetaRNN computational evidence supports a deleterious effect, 0.992
• PP5: Variant 7-39999458-G-C is Pathogenic according to our data. Variant chr7-39999458-G-C is described in ClinVar as [Pathogenic]. Clinvar id is 375738.Status of the report is no_assertion_criteria_provided, 0 stars.
