GENE SUMMARY |
---|
The protein encoded by this gene is involved in the conversion of tyrosine to dopamine. It is the rate-limiting enzyme in the synthesis of catecholamines, hence plays a key role in the physiology of adrenergic neurons. Mutations in this gene have been associated with autosomal recessive Segawa syndrome. Alternatively spliced transcript variants encoding different isoforms have been noted for this gene.

Complication | Evidence | PMID |
Retinopathy | 1. It is reported that retinal dopamine and tyrosine hydroxylase protein levels are downregulated, and dopaminergic amacrine cells appear to be degenerating in the animal models of DR. | 26141638 |
Neuropathy | 1. In the early stage of STZ diabetic, the administration of Ad.BDNF into the vitreous cavities can increase TH protein levels and the density of dopaminergic amacrine cells in the STZ rats' retina. | 22553539 |
