<unk>  <unk>  is a rare X-linked non-progressive retinal disorder. It has two forms, complete, also known as type-1<unk> , and incomplete, also known as type-2 <unk> , depending on severity. In the complete form<unk> , there is no measurable rod cell response to<unk> , whereas this response is measurable in the incomplete form. Patients with this disorder have difficulty adapting to low<unk>  situations due to impaired photoreceptor transmission. These patients also often have reduced visual acuity, myopia, nystagmus, and strabismus.<unk>  is caused by mutations in the gene NYX, which encodes a protein involved in retinal synapse formation or synaptic transmission.<unk>  is caused by mutations in the gene CACNA1F, which encodes a voltage-gated calcium channel CaV1.4.
