Genes affected

LMX1A (HGNC:6653): (LIM homeobox transcription factor 1 alpha) This gene encodes a homeodomain and LIM-domain containing protein. The encoded protein is a transcription factor that acts as a positive regulator of insulin gene transcription. This gene also plays a role in the development of dopamine producing neurons during embryogenesis. Mutations in this gene are associated with an increased risk of developing Parkinson's disease. Alternate splicing results in multiple transcript variants. [provided by RefSeq, Feb 2012]

LMX1A-AS2 (HGNC:40343): (LMX1A antisense RNA 2)

ACMG classification

Our verdict: Uncertain_significance. The variant received 0 ACMG points.
