While SCD mutations have not been directly identified, there are numerous Parkinson’s risk factors that function in lipid metabolism or related functions, such as GBA, LRRK2, RAB7, VPS35, SYNJ1, ELOVL7, SCARB2, and SREBF-1, which is a transcription factor that regulates expression of lipogenic genes, including SCD [27, 28]. The gene discussed is SCD; the disease is Parkinsonism.
