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]

Submissions by phenotype

Inborn genetic diseases Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 28, 2023The c.6317A>G (p.D2106G) alteration is located in exon 36 (coding exon 34) of the BAZ2B gene. This alteration results from a A to G substitution at nucleotide position 6317, causing the aspartic acid (D) at amino acid position 2106 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
