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]

Collection Method:clinical testing

The c.872C>T (p.T291M) alteration is located in exon 8 (coding exon 7) of the LMX1A gene. This alteration results from a C to T substitution at nucleotide position 872, causing the threonine (T) at amino acid position 291 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
