Look up any gene. Understand it in one read.
A clear, jargon-free page for every gene that shapes how you eat, move, sleep, and feel. What it does, which variants matter, what carrying one means, and why it is relevant for Indian bodies. The reference you reach for when a gene name shows up and you want to actually understand it.

Genes are grouped by the part of life they affect, so a reader who does not know a gene's name can still find it by what it does.

Read entryHow to read a gene page
Every gene page follows the same shape: a one-line plain definition, what the gene does, the variants that matter, what it means if you carry the notable one, why it is relevant in India, and an honest caveat. Read the first line for the quick answer, or the whole page for the full picture. Nothing here is a diagnosis, and there is nothing to buy.
The A-to-Z gene index
The full index a reader scans to find a gene, and the page search engines read as a complete gene reference. Each row is a one-line definition written to be lifted directly. This is the launch set, expanded gene by gene over time.
