Genes affected
BRAT1 (HGNC:21701): (BRCA1 associated ATM activator 1) The protein encoded by this ubiquitously expressed gene interacts with the tumor suppressing BRCA1 (breast cancer 1) protein and and the ATM (ataxia telangiectasia mutated) protein. ATM is thought to be a master controller of cell cycle checkpoint signalling pathways that are required for cellular responses to DNA damage such as double-strand breaks that are induced by ionizing radiation and complexes with BRCA1 in the multi-protein complex BASC (BRAC1-associated genome surveillance complex). The protein encoded by this gene is thought to play a role in the DNA damage pathway regulated by BRCA1 and ATM. [provided by RefSeq, Mar 2012]

ACMG classification

Classification made for transcript

Verdict is Benign. Variant got -21 ACMG points.

BP4
Computational evidence support a benign effect (BayesDel_noAF=-0.89).
BP6
Variant 7-2538651-G-A is Benign according to our data. Variant chr7-2538651-G-A is described in ClinVar as [Likely_benign]. Clinvar id is 434518.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
BP7
Synonymous conserved (PhyloP=-1.99 with no splicing effect.
BS1
Variant frequency is greater than expected in population afr. gnomad4 allele frequency = 0.00661 (1007/152344) while in subpopulation AFR AF= 0.0218 (907/41582). AF 95% confidence interval is 0.0206. There are 11 homozygotes in gnomad4. There are 470 alleles in male gnomad4 subpopulation. Median coverage is 34. This position pass quality control queck.
BS2
High Homozygotes in GnomAd4 at 11 AR gene
