This variant is present in population databases (rs761068277, gnomAD 0.0009%). This missense change has been observed in individual(s) with ABCA12-related conditions (PMID: 30578701, 36980989). ClinVar contains an entry for this variant (Variation ID: 633801). Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) has been performed at Invitae for this missense variant, however the output from this modeling did not meet the statistical confidence thresholds required to predict the impact of this variant on ABCA12 protein function. This variant disrupts the p.Arg2426 amino acid residue in ABCA12. Other variant(s) that disrupt this residue have been determined to be pathogenic (PMID: 30578701). This suggests that this residue is clinically significant, and that variants that disrupt this residue are likely to be disease-causing. In summary, the currently available evidence indicates that the variant is pathogenic, but additional data are needed to prove that conclusively. Therefore, this variant has been classified as Likely Pathogenic.
