However, the E266G variant has been published in association with systemic lupus erythematosus (SLE) (Namjou et al., 2011; Lee-Kirsch et al., 2007). Namjou et al., reports identifying the E266G variant in 5 patients of African decent diagnosed with SLE but not in ethnically matched controls (Namjou et al., 2011). This variant was also identified identified in members of the cohort of European decent but also within ethnically matched controls (Namjou et al., 2011). The NHLBI Exome Sequencing Project reports E266G was observed in 33/8600 (0.38%) alleles from individuals of European background, and the 1000 Genomes Project Consortium reports E266G was observed in 1/978 (0.1%) alleles from individuals of South Asian background. The E266G 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 not conserved. In silico analysis predicts this variant likely does not alter the protein structure/function. Therefore, based on the currently available information, it is unclear whether this variant is a pathogenic variant or a rare benign variant.
