Genes affected
GUCA1A (HGNC:4678): (guanylate cyclase activator 1A) This gene encodes an enzyme that plays a role in the recovery of retinal photoreceptors from photobleaching. This enzyme promotes the activity of retinal guanylyl cyclase-1 (GC1) at low calcium concentrations and inhibits GC1 at high calcium concentrations. Mutations in this gene can cause cone dystrophy 3 and code-rod dystrophy 14. provided by RefSeq, Jul 2020]
ENSG00000290147 (HGNC:56129): (GUCA1ANB-GUCA1A readthrough) This locus represents naturally occurring readthrough transcription between the neighboring GUCA1ANB (GUCA1A neighbor) and GUCA1A (guanylate cyclase activator 1A) genes on chromosome 6. The readthrough transcript encodes the same protein as GUCA1A. [provided by RefSeq, Jul 2020]
