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]

The c.6095A>T (p.D2032V) alteration is located in exon 35 (coding exon 33) of the BAZ2B gene. This alteration results from a A to T substitution at nucleotide position 6095, causing the aspartic acid (D) at amino acid position 2032 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
