Variants pathogenicity by type

Statistics on ClinVar variants can assist in determining whether a specific variant type in the RNF43 gene is commonly pathogenic or not. These statistics are base on transcript: NM_000017763.6. 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: E3 ubiquitin-protein ligase that acts as a negative regulator of the Wnt signaling pathway by mediating the ubiquitination, endocytosis and subsequent degradation of Wnt receptor complex components Frizzled. Acts on both canonical and non-canonical Wnt signaling pathway. Acts as a tumor suppressor in the intestinal stem cell zone by inhibiting the Wnt signaling pathway, thereby resticting the size of the intestinal stem cell zone. {ECO:0000269|PubMed:18313049, ECO:0000269|PubMed:22575959, ECO:0000269|PubMed:22895187}.;
Disease: DISEASE: Sessile serrated polyposis cancer syndrome (SSPCS) [MIM:617108]: A rare disease characterized by multiple and/or large serrated polyps developing in the colon, and an increased personal and familial risk of colorectal cancer. A patient is diagnosed with SSPCS if at least one of the following criteria is met: the presence of at least five sessile serrated polyps proximal to the sigmoid colon, two of which are greater than 10 mm in diameter; the presence of any number of serrated polyps occurring proximal to the sigmoid colon in an individual who has a first-degree relative with serrated polyposis; the presence of more than 20 serrated polyps of any size distributed throughout the colon. Sessile serrated polyps are also known as sessile serrated adenomas (SSA) and are estimated to be responsible for 20 to 35% of all colon cancers. Individuals with SSPCS may have a strong personal or family history of extracolonic cancers. {ECO:0000269|PubMed:24512911, ECO:0000269|PubMed:27081527}. Note=Disease susceptibility may be associated with variations affecting the gene represented in this entry.;
