The c.731_733delAAG variant in the SBDS gene causes an in-frame of codon Glutamic acid 244. The c.731_733delAAG variant has not been published as a pathogenic variant, nor has it been reported as a benign variant to our knowledge. However, this variant was observed with a pathogenic variant on the opposite allele (in trans) in this patient. The c.731_733delAAG variant is not observed at a significant frequency in large population cohorts (Lek et al., 2016; 1000 Genomes Consortium et al., 2015; Exome Variant Server). This variant occurs at a position that is conserved across species. In silico analysis predicts this variant is probably damaging to the protein structure/function. Based on the currently available information, c.731_733delAAG is a strong candidate for a pathogenic variant. However, the possibility it may be a rare benign variant cannot be excluded. -
