Genes affected

ENSG00000290074 (HGNC:):

MCL1 (HGNC:6943): (MCL1 apoptosis regulator, BCL2 family member) This gene encodes an anti-apoptotic protein, which is a member of the Bcl-2 family. Alternative splicing results in multiple transcript variants. The longest gene product (isoform 1) enhances cell survival by inhibiting apoptosis while the alternatively spliced shorter gene products (isoform 2 and isoform 3) promote apoptosis and are death-inducing.

ACMG classification

Our verdict: Benign. The variant received -10 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.43).
• BA1: GnomAd4 highest subpopulation (NFE) allele frequency at 95% confidence interval = 0.542 is higher than 0.05.
