Genes affected

MYBL2 (HGNC:7548): (MYB proto-oncogene like 2) The protein encoded by this gene, a member of the MYB family of transcription factor genes, is a nuclear protein involved in cell cycle progression. The encoded protein is phosphorylated by cyclin A/cyclin-dependent kinase 2 during the S-phase of the cell cycle and possesses both activator and repressor activities. It has been shown to activate the cell division cycle 2, cyclin D1, and insulin-like growth factor-binding protein 5 genes. Two transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Jul 2013]

ACMG classification

Verdict is Benign. Variant got -12 ACMG points.

• BP4: Computational evidence support a benign effect (MetaRNN=0.001899004).
• BA1: GnomAd4 highest subpopulation (NFE) allele frequency at 95% confidence interval = 0.0576 is higher than 0.05.
