Variant summary

Our verdict is Likely benign. The variant received -1 ACMG points: 1P and 2B. PP2BP4_Moderate

The NM_000180.4(GUCY2D):​c.43G>A​(p.Gly15Arg) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.000023 in 1,524,646 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 15/22 in silico tools predict a benign outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (★). Synonymous variant affecting the same amino acid position (i.e. G15G) has been classified as Likely benign.

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.

ACMG classification

Classification was made for transcript

Our verdict: Likely_benign. The variant received -1 ACMG points.

PP2
Missense variant in the gene, where a lot of missense mutations are associated with disease in ClinVar. The gene has 55 curated pathogenic missense variants (we use a threshold of 10). The gene has 15 curated benign missense variants. Gene score misZ: 0.78087 (below the threshold of 3.09). Trascript score misZ: 0.0082692 (below the threshold of 3.09). GenCC associations: The gene is linked to Leber congenital amaurosis 1, GUCY2D-related dominant retinopathy, central areolar choroidal dystrophy, cone-rod dystrophy, cone-rod dystrophy 6, night blindness, congenital stationary, type1i, GUCY2D-related recessive retinopathy, Leber congenital amaurosis.
BP4
Computational evidence support a benign effect (MetaRNN=0.082687885).
