Description

The OPA3 c.123C>G variant is predicted to result in the amino acid substitution p.Ile41Met. This variant has been reported in the heterozygous state in patients with optic atrophy with or without cataracts (Chen et al 2014. PubMed ID: 25205859; Fan et al. 2020. PubMed ID: 32883240; Li et al. 2020. PubMed ID: 32855858). Inheritance from affected and unaffected parents has been documented and suggests that this variant may be incompletely penetrant (Fan et al. 2020. PubMed ID: 32883240). This variant is reported in 0.082% of alleles in individuals of East Asian descent in gnomAD (http://gnomad.broadinstitute.org/variant/19-46087900-G-C). This variant has been interpreted by the majority of submitters in ClinVar as uncertain (https://www.ncbi.nlm.nih.gov/clinvar/variation/894212). Although we suspect that this variant may be pathogenic, at this time, the clinical significance of this variant is uncertain due to the absence of conclusive functional and genetic evidence.
