The p.Asn700Ser variant (rs142694017) has not been reported in the medical literature, is not listed in gene-specific variant databases, nor has it been previously identified in our laboratory. It is listed in the Genome Aggregation Database (gnomAD) browser with a frequency in African populations of 0.037% (identified in 9 out of 24,028 chromosomes). The asparagine at codon 700 is moderately conserved considering 12 species (Alamut software v2.9), and computational analyses return mixed results regarding the effect of this variant on OPA1 protein structure/function (SIFT: tolerated, PolyPhen2: benign, and Mutation Taster: disease causing). Thus, based on the available information, the clinical significance of the p.Asn700Ser variant cannot be determined with certainty.
