Genes affected

MAML1 (HGNC:13632): (mastermind like transcriptional coactivator 1) This protein is the human homolog of mastermind, a Drosophila protein that plays a role in the Notch signaling pathway involved in cell-fate determination. There is in vitro evidence that the human homolog forms a complex with the intracellular portion of human Notch receptors and can increase expression of a Notch-induced gene. This evidence supports its proposed function as a transcriptional co-activator in the Notch signaling pathway. [provided by RefSeq, Jul 2008]

ACMG classification

Our verdict: Benign. The variant received -12 ACMG points.

• BP4: Computational evidence support a benign effect (MetaRNN=0.0026194751).
• BA1: GnomAd4 highest subpopulation (NFE) allele frequency at 95% confidence interval = 0.339 is higher than 0.05.
