LMX1A is known to be a key transcription factor associated with dopamine (DA) neurogenesis in the midbrain (Andersson et al. 2006, Yan et al. 2011, Doucet-Beaupré et al. 2015, Rolstad et al. 2015) and is linked to neurodevelopmental and neurodegenerative DA-related diseases such as Parkinson’s disease (Cai et al. 2009, Laguna et al. 2015). This evidence concerns the gene LMX1A and Parkinson disease.
