Genes affected

BAZ2B (HGNC:963): (bromodomain adjacent to zinc finger domain 2B) This gene belongs to the bromodomain gene family. Members of this gene family encode proteins that are integral components of chromatin remodeling complexes. The encoded protein showed strong preference for the activating H3K14Ac mark in a histone peptide screen, suggesting a potential role in transcriptional activation. This gene may be associated with susceptibility to sudden cardiac death (SCD). [provided by RefSeq, Aug 2016]

BAZ2B Gene-Disease associations (from GenCC):

• neurodevelopmental disorder

  Inheritance: AD Classification: STRONG, LIMITED Submitted by: G2P, Ambry Genetics
• complex neurodevelopmental disorder

  Inheritance: AD Classification: LIMITED Submitted by: ClinGen

ACMG classification

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

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.83).
• BA1: GnomAd4 highest subpopulation (NFE) allele frequency at 95% confidence interval = 0.982 is higher than 0.05.
