Your ABO blood type is written in one gene on chromosome 9. Learn how rs8176719 and rs8176746 shape A, B, AB, and O — and why 23andMe raw data can't always report it directly.
Eye color is written in your genes — mostly OCA2 and HERC2. Learn what rs12913832 means, why two brown-eyed parents can have a blue-eyed child, and what your DNA shows.
The VHL gene is a tumor suppressor linked to hereditary kidney cancer. Learn what VHL does, how hereditary kidney cancer differs from sporadic, and why this is a topic for a doctor, not a raw DNA file.
Learn what the GLP1R gene does, why it's studied for GLP-1 medication response, and why genetics alone can't predict individual outcomes.
What genetic testing for weight loss actually reveals: appetite genes, insulin genes, GLP-1 response — and its real limits.
Peptides for weight loss explained: what they are, the genetics behind GLP-1 response, and why any peptide decision belongs with a doctor.
What the MC4R gene does in appetite and body weight, how it differs from rare monogenic obesity, and why satiety biology matters for GLP-1 discussions.
The FTO gene is linked to appetite and body weight. Learn what rs9939609 and rs1421085 mean, and what research says about weight-loss approaches.
