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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsSep 17, 2021The c.32A>G (p.D11G) alteration is located in exon 2 (coding exon 2) of the MYBL2 gene. This alteration results from a A to G substitution at nucleotide position 32, causing the aspartic acid (D) at amino acid position 11 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
