A new study has come up empty-handed after pursuing a genetic explanation for why one identical twin developed multiple sclerosis while the other stayed healthy.

Researchers transcribed the complete genetic blueprints for a pair of identical twins, looking for differences that might explain why one has multiple sclerosis and the other does not. No trace of what caused the discrepancy appeared in the twins’ DNA. And scientists found no smoking gun when they compared levels of gene activity b...
