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]

Submissions by phenotype

Neonatal-onset encephalopathy with rigidity and seizures Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingInvitaeSep 06, 2022This variant, c.590_592del, results in the deletion of 1 amino acid(s) of the BRAT1 protein (p.Lys197del), but otherwise preserves the integrity of the reading frame. This variant is present in population databases (rs747567777, gnomAD 0.0009%). This variant has not been reported in the literature in individuals affected with BRAT1-related conditions. ClinVar contains an entry for this variant (Variation ID: 472973). 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. -
