Every claim sourced. Every entry dated.

Ongoing work on ancestral North and South Indian components, drawing on ancient genomes, continues to add nuance to a long-contested history of migration and mixing.

Implementation of the Digital Personal Data Protection Act keeps clarifying obligations for companies that process sensitive personal data, including genetic information.

The national effort to map the genetic variation of India's many populations continues to expand its reference database, addressing decades of underrepresentation in global genomics.

Researchers report refined estimates of how few South Asian adults carry the lactase-persistence variant, with meaningful regional variation across the subcontinent.

More health systems are testing genes that govern drug response before starting certain psychiatric, cardiac, and pain medications, reducing months of trial and error.

Fresh reviews find that scores summing thousands of small genetic effects can flag above-average risk for conditions like diabetes and heart disease, but remain weak predictors for any single individual.

A reader wrote in confused. Three years ago their ancestry report said one thing. This year, same saliva, same company, it says something noticeably different. Did the lab make a mistake? Did their DNA somehow change? Neither. What changed was everything around the DNA.

Half of all adults clear caffeine slowly, and for them a 2pm coffee is still circulating at midnight. The CYP1A2 gene decides which half you fall into - and the implication runs deeper than sleep.

India's Digital Personal Data Protection Act treats genetic information as sensitive personal data. The detail of how that protection works in practice is still being filled in - and it matters for anyone considering a consumer DNA test.

Heart disease in South Asians presents earlier, hits at lower body weights, and progresses faster than in most other populations. The genetics, the diet, and the metabolism each contribute - and the action items are clearer than the conversation usually admits.
