Variants pathogenicity by type

Statistics on ClinVar variants can assist in determining whether a specific variant type in the GUCA1A gene is commonly pathogenic or not. These statistics are base on transcript: NM_001384910.1. Only rare variants are included in the table.

In the table, we include only reliable ClinVar variants with their consequences to MANE Select, Mane Plus Clinical transcripts, or transcripts with TSL equals 1. Click the count to view the source variants.

Warning: slight differences between displayed counts and the number of variants in ClinVar may occur, primarily due to (1) the application of a different transcript and/or consequence by our variant effect predictor or (2) differences in clinical significance: we classify Benign/Likely benign variants as Likely benign and Pathogenic/Likely pathogenic variants as Likely pathogenic.

Function
FUNCTION: Stimulates retinal guanylyl cyclase when free calcium ions concentration is low and inhibits guanylyl cyclase when free calcium ions concentration is elevated (PubMed:19459154). This Ca(2+)-sensitive regulation of retinal guanylyl cyclase is a key event in recovery of the dark state of rod photoreceptors following light exposure. {ECO:0000269|PubMed:19459154, ECO:0000305}.;
Disease
DISEASE: Cone dystrophy 3 (COD3) [MIM:602093]: An autosomal dominant cone dystrophy. Cone dystrophies are retinal dystrophies characterized by progressive degeneration of the cone photoreceptors with preservation of rod function, as indicated by electroretinogram. However, some rod involvement may be present in some cone dystrophies, particularly at late stage. Affected individuals suffer from photophobia, loss of visual acuity, color vision and central visual field. Another sign is the absence of macular lesions for many years. Cone dystrophies are distinguished from the cone-rod dystrophies in which some loss of peripheral vision also occurs. {ECO:0000269|PubMed:11108966, ECO:0000269|PubMed:11146732, ECO:0000269|PubMed:11484154, ECO:0000269|PubMed:15505030, ECO:0000269|PubMed:15735604, ECO:0000269|PubMed:15790869, ECO:0000269|PubMed:19459154, ECO:0000269|PubMed:9425234}.
