Genes affected
GUCY2D (HGNC:4689): (guanylate cyclase 2D, retinal) This gene encodes a retina-specific guanylate cyclase, which is a member of the membrane guanylyl cyclase family. Like other membrane guanylyl cyclases, this enzyme has a hydrophobic amino-terminal signal sequence followed by a large extracellular domain, a single membrane spanning domain, a kinase homology domain, and a guanylyl cyclase catalytic domain. In contrast to other membrane guanylyl cyclases, this enzyme is not activated by natriuretic peptides. Mutations in this gene result in Leber congenital amaurosis and cone-rod dystrophy-6 diseases.

Pathogenic, criteria provided, single submitter | clinical testing | Invitae | Mar 09, 2023 | For these reasons, this variant has been classified as Pathogenic. This variant has not been reported in the literature in individuals affected with GUCY2D-related conditions. This variant is not present in population databases (gnomAD no frequency). This sequence change creates a premature translational stop signal (p.Cys17*) in the GUCY2D gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in GUCY2D are known to be pathogenic (PMID: 10951519, 11328726). - |
