Genes affected

BRD3 (HGNC:1104): (bromodomain containing 3) This gene was identified based on its homology to the gene encoding the RING3 protein, a serine/threonine kinase. The gene localizes to 9q34, a region which contains several major histocompatibility complex (MHC) genes. The function of the encoded protein is not known. [provided by RefSeq, Jul 2008]

The c.904G>A (p.A302T) alteration is located in exon 6 (coding exon 5) of the BRD3 gene. This alteration results from a G to A substitution at nucleotide position 904, causing the alanine (A) at amino acid position 302 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
