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]

GUCA1A links:

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]

Significance: Likely benign

Review Status: criteria provided, single submitter

Collection Method: clinical testing

This variant was observed as part of a predisposition screen in an ostensibly healthy population. A literature search was performed for the gene, cDNA change, and amino acid change (where applicable). No publications were found based on this search. Allele frequency data from public databases allowed determination this variant is unlikely to cause disease. Therefore, this variant is classified as likely benign. -
