Genes affected

CREB1 (HGNC:2345): (cAMP responsive element binding protein 1) This gene encodes a transcription factor that is a member of the leucine zipper family of DNA binding proteins. This protein binds as a homodimer to the cAMP-responsive element, an octameric palindrome. The protein is phosphorylated by several protein kinases, and induces transcription of genes in response to hormonal stimulation of the cAMP pathway. Alternate splicing of this gene results in several transcript variants encoding different isoforms. [provided by RefSeq, Mar 2016]

METTL21A (HGNC:30476): (methyltransferase 21A, HSPA lysine) Enables ATPase binding activity; Hsp70 protein binding activity; and protein-lysine N-methyltransferase activity. Involved in peptidyl-lysine methylation. Part of protein-containing complex. [provided by Alliance of Genome Resources, Apr 2022]

CREB1 (HGNC:):

ACMG classification

Verdict is Benign. Variant got -10 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.38).
• BA1: GnomAd4 highest subpopulation (EAS) allele frequency at 95% confidence interval = 0.976 is higher than 0.05.
