Score is the Open Targets composite evidence score (0-1). Higher = stronger gene-disease association.

Protein function (UniProt)

Visual system homeobox 1

Binds to the 37-bp core of the locus control region (LCR) of the red/green visual pigment gene cluster (PubMed:10903837). May regulate the activity of the LCR and the cone opsin genes at earlier stages of development (PubMed:10903837). Dispensable in early retinal development (By similarity)
