Copy Number Variation (CNV): When Whole Chunks of DNA Are Deleted or Duplicated, and How It Differs from SNPs

Dr. Kaet (Lukkaet Laoprapaipan)

Sep 03, 2026

How DNA Reconstructs Your Ancestral 'Migration Map'

Dr. Kaet (Lukkaet Laoprapaipan)

Aug 31, 2026

Ancestry testing doesn't find a "60% Thai" label inside your DNA. It's statistical inference from SNPs and haplogroups matched to global reference populations — rebuilding your ancestors' migration map.

Same Drug, Different Results? The Science of Pharmacogenomics

Dr. Kaet (Lukkaet Laoprapaipan)

Aug 31, 2026

Two patients, same drug, same dose — one recovers, one has side effects. The answer is in CYP450 genes that set how fast you metabolize drugs. This is pharmacogenomics, the heart of precision medicine.
