Genetic association has been found between the LMX1B gene and autism in a Caucasian AGRE cohort (Thanseem et al., 2011), with two SNPs (rs10732392 and rs12336217) showing moderate association with autism with p values of 0.018 and 0.022, respectively, in a transmission disequilibrium test. LMX1B transcripts were found to be significantly lower in the anterior cingulate gyrus region of autism patients compared with controls (p=0.049) in this report.
Molecular Function
This gene encodes a member of the LIM-homeodomain family of proteins containing two N-terminal zinc-binding LIM domains, 1 homeodomain, and a C-terminal glutamine-rich domain. It functions as a transcription factor, and is essential for the normal development of dorsal limb structures, the glomerular basement membrane, the anterior segment of the eye, and dopaminergic and serotonergic neurons.
