Among the predicted 32 candidate genes, SWI/SNF‐related, matrix‐associated, actin‐dependent regulator of chromatin, subfamily A, member 4 (SMARCA4) and biliverdin reductase A (BLVRA) were further studied in vivo using Drosophila melanogaster, and their potential involvement in PD pathogenesis was confirmed. This evidence concerns the gene BLVRA and Parkinson disease.
