Variant summary

Our verdict is Benign. Variant got -12 ACMG points: 0P and 12B. BP4_StrongBS1BS2

The NM_005104.4(BRD2):ā€‹c.146C>Gā€‹(p.Ala49Gly) variant causes a missense change. The variant allele was found at a frequency of 0.0155 in 1,614,232 control chromosomes in the GnomAD database, including 270 homozygotes. In-silico tool predicts a benign outcome for this variant. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar. Another nucleotide change resulting in same amino acid change has been previously reported as Likely benignin UniProt. Another variant affecting the same amino acid position, but resulting in a different missense (i.e. A49S) has been classified as Likely benign.

Genes affected
BRD2 (HGNC:1103): (bromodomain containing 2) This gene encodes a transcriptional regulator that belongs to the BET (bromodomains and extra terminal domain) family of proteins. This protein associates with transcription complexes and with acetylated chromatin during mitosis, and it selectively binds to the acetylated lysine-12 residue of histone H4 via its two bromodomains. The gene maps to the major histocompatability complex (MHC) class II region on chromosome 6p21.3, but sequence comparison suggests that the protein is not involved in the immune response. This gene has been implicated in juvenile myoclonic epilepsy, a common form of epilepsy that becomes apparent in adolescence. Multiple alternatively spliced variants have been described for this gene. [provided by RefSeq, Dec 2010]

ACMG classification

Classification made for transcript

Verdict is Benign. Variant got -12 ACMG points.

BP4
Computational evidence support a benign effect (MetaRNN=0.0046857).
BS1
Variant frequency is greater than expected in population sas. gnomad4 allele frequency = 0.0124 (1895/152348) while in subpopulation SAS AF= 0.029 (140/4824). AF 95% confidence interval is 0.0251. There are 18 homozygotes in gnomad4. There are 951 alleles in male gnomad4 subpopulation. Median coverage is 32. This position pass quality control queck.
BS2
High Homozygotes in GnomAd4 at 18 gene
