RCV000255518 | SCV000321419 | likely pathogenic | not provided | 2016-01-04 | criteria provided, single submitter | clinical testing | The R609W variant in the BRAT1 gene has now been reported by Hanes et al. (2015) in a child with lethal neonatal rigidity and seizure syndrome and the c.294dupA variant on the opposite BRAT1 allele, who is likely this individual's niece. The R609W variant was not observed in approximately 6400 individuals of European and African American ancestry in the NHLBI Exome Sequencing Project, indicating it is not a common benign variant in these populations. The R609W variant is a non-conservative amino acid substitution, which is likely to impact secondary protein structure as these residues differ in polarity, charge, size and/or other properties. This substitution occurs at a position that is conserved across species. In silico analysis predicts this variant is probably damaging to the protein structure/function. The R609W variant is a strong candidate for a pathogenic variant, however the possibility it may be a rare benign variant cannot be excluded. |
