Molecular assay reagents intended to identify mutations in the cyclic nucleotide gated channel beta 1 (CNGB1) gene, located at chromosome 16q13, which encodes for cyclic guanine nucleotide-gated channel (cGMP) rod photoreceptor that plays a role in photoreceptor cell generation. Mutations at this locus have been identified in patients with retinitis pigmentosa.
