The one axis you can check on yourself: variants that change the perception rather than the odds.
Why this topic Everything else here is a probability. This is the part a reader can test at dinner.
Solid lines are connections this site curates. Dashed lines mean the two ends share a research paper — worth knowing, and not a claim that one explains the other.
Counted in Europe PMC, where the title or abstract names both this topic and that rsID. The number is papers, not evidence of a cause.

Smell and taste is this site's topic page for chemosensory genetics — the one axis here where a variant changes what someone actually perceives, not just the odds of something happening.
Some genuinely do — chemosensory variants change perception itself rather than shifting a risk, which makes this the rare part of the site a reader can check against their own experience at dinner.
This page counts co-mentions — papers naming both a smell-or-taste term and a variant. The dedicated smell-and-taste page is a curated index of the specific chemosensory groups those variants belong to, built from the variant and condition pages themselves.
Europe PMC is searched for bitter taste perception, olfactory receptor, specific anosmia or taste perception appearing in a paper's title or abstract alongside a published rsID, recounted every month.
