Genes affected

BRD4 (HGNC:13575): (bromodomain containing 4) The protein encoded by this gene is homologous to the murine protein MCAP, which associates with chromosomes during mitosis, and to the human RING3 protein, a serine/threonine kinase. Each of these proteins contains two bromodomains, a conserved sequence motif which may be involved in chromatin targeting. This gene has been implicated as the chromosome 19 target of translocation t(15;19)(q13;p13.1), which defines an upper respiratory tract carcinoma in young people. Two alternatively spliced transcript variants have been described. [provided by RefSeq, Jul 2008]

This variant, c.3915_3917dup, results in the insertion of 1 amino acid(s) of the BRD4 protein (p.Ala1308dup), but otherwise preserves the integrity of the reading frame. This variant is present in population databases (rs779357037, gnomAD 0.02%). This variant has not been reported in the literature in individuals affected with BRD4-related conditions. ClinVar contains an entry for this variant (Variation ID: 2071932). Experimental studies and prediction algorithms are not available or were not evaluated, and the functional significance of this variant is currently unknown. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. -
