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]

BRD4 (HGNC:):

ACMG classification

Verdict is Benign. Variant got -20 ACMG points.

• BP4: Computational evidence support a benign effect (MetaRNN=0.0067904294).
• BP6: Variant 19-15238785-C-A is Benign according to our data. Variant chr19-15238785-C-A is described in ClinVar as [Benign]. Clinvar id is 718290.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
• BS1: Variant frequency is greater than expected in population amr. gnomad4_exome allele frequency = 0.0008 (1146/1432168) while in subpopulation AMR AF= 0.0214 (898/42058). AF 95% confidence interval is 0.0202. There are 12 homozygotes in gnomad4_exome. There are 502 alleles in male gnomad4_exome subpopulation. Median coverage is 32. This position pass quality control queck.
• BS2: High AC in GnomAd4 at 154 AD gene.
