Interestingly, in this study (Dorval et al., 2014), miR-103 was found to be down-regulated in transgenic mice expressing PD-associated LRRK2 R1441G mutation when compared to wildtype mice, yet no information of the direct regulation or predicted site of miR-103 in LRRK2 gene was observed. The gene discussed is LRRK2; the disease is Parkinson disease.
