Strain Description

Phenotype

Homozygous: Decline in rod visual sensitivity and severe impairment of nocturnal vision due to the reduction in signal amplification in rods, which manifests as night blindness. Slow progressive retina degeneration. Normal viability and normal fertility for both hets and homozygotes.

Heterozygous: Essentially wild type regarding signaling in rods and the absence of retina degeneration. Small physiologically inconsequential changes in transducin subunit expression in rods.
