Genes affected

BRD1 (HGNC:1102): (bromodomain containing 1) This gene encodes a bromodomain-containing protein that localizes to the nucleus and can interact with DNA and histone tails. The encoded protein is a component of the MOZ/MORF acetyltransferase complex and can stimulate acetylation of histones H3 and H4, thereby potentially playing a role in gene activation. Variation in this gene is associated with schizophrenia and bipolar disorder in some study populations. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Mar 2017]

The c.2884G>A (p.V962I) alteration is located in exon 11 (coding exon 11) of the BRD1 gene. This alteration results from a G to A substitution at nucleotide position 2884, causing the valine (V) at amino acid position 962 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
