Variants pathogenicity by type

Statistics on ClinVar variants can assist in determining whether a specific variant type in the TAS2R8 gene is commonly pathogenic or not.

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: Receptor that may play a role in the perception of bitterness and is gustducin-linked. May play a role in sensing the chemical composition of the gastrointestinal content. The activity of this receptor may stimulate alpha gustducin, mediate PLC-beta-2 activation and lead to the gating of TRPM5.
• Pathway: Taste transduction - Homo sapiens (human);Signaling by GPCR;Signal Transduction;Class C/3 (Metabotropic glutamate/pheromone receptors);GPCR ligand binding;G alpha (i) signalling events;GPCR downstream signalling (Consensus)
