Description

A variant of uncertain significance has been identified in the CLN3 gene. The R255K variant has not been published as a pathogenic variant, nor has it been reported as a benign variant to our knowledge. The R255K variant is a conservative amino acid substitution, which is not likely to impact secondary protein structure as these residues share similar properties. This substitution occurs at a position that is not conserved and in silico analysis predicts this variant likely does not alter the protein structure/function. However, the R255K variant was not observed in approximately 6,500 individuals of European and African American ancestry in the NHLBI Exome Sequencing Project, indicating it is not a common benign variant in these populations. Therefore, based on the currently available information, it is unclear whether this variant is a pathogenic variant or a rare benign variant.
