Genes affected

CDK10 (HGNC:1770): (cyclin dependent kinase 10) The protein encoded by this gene belongs to the CDK subfamily of the Ser/Thr protein kinase family. The CDK subfamily members are highly similar to the gene products of S. cerevisiae cdc28, and S. pombe cdc2, and are known to be essential for cell cycle progression. This kinase has been shown to play a role in cellular proliferation and its function is limited to cell cycle G2-M phase. Multiple transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, May 2009]

ACMG classification

Verdict is Pathogenic. Variant got 18 ACMG points.

• PVS1: Splicing +-2 bp (donor or acceptor) variant, LoF is a know mechanism of disease, No cryptic splice site detected. Exon removal results in frameshift change.
• PM2: Very rare variant in population databases, with high coverage
• PP5: Variant 16-89693468-G-A is Pathogenic according to our data. Variant chr16-89693468-G-A is described in ClinVar as [Pathogenic]. Clinvar id is 440757.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars. Variant chr16-89693468-G-A is described in Lovd as [Pathogenic].
