Genes affected

CDC14A (HGNC:1718): (cell division cycle 14A) The protein encoded by this gene is a member of the dual specificity protein tyrosine phosphatase family. It is highly similar to Saccharomyces cerevisiae Cdc14, a protein tyrosine phosphatase involved in the exit of cell mitosis and initiation of DNA replication, suggesting a role in cell cycle control. This protein has been shown to interact with, and dephosphorylate tumor suppressor protein p53, and is thought to regulate the function of p53. Alternative splicing of this gene results in several transcript variants encoding distinct isoforms. [provided by RefSeq, Jul 2008]

ACMG classification

Verdict is Pathogenic. Variant got 11 ACMG points.

• PVS1: Loss of function variant, product undergoes nonsense mediated mRNA decay. LoF is a known mechanism of disease.
• PM2: Very rare variant in population databases, with high coverage
• PP5: Variant 1-100424287-CT-C is Pathogenic according to our data. Variant chr1-100424287-CT-C is described in ClinVar as [Pathogenic]. Clinvar id is 559437.Status of the report is no_assertion_criteria_provided, 0 stars. Variant chr1-100424287-CT-C is described in Lovd as [Pathogenic].
