Paris: A Japanese has joined the elite clubof humans whose genetic code has been fully sequenced,according to research unveiled on Sunday. The unnamed male gave a sample of DNA which has beenunravelled to show all three billion base pairs, or "letters"in the double-helix code for life. Six other genomes are reported to have been fullysequenced since 2001.
The project aims at shedding light on genetic variationsthat can explain inherited vulnerability to disease, tailordrugs to individual needs and help explain the odyssey ofhuman migration. In email exchange with AFP, Tsunoda said he was cautiousabout making any early comparison between the Japanese and theother known genomes, as the seven sequencing projects useddifferent methods to unravel the DNA and analyse it. "More samples -- dozens -- would be necessary, which isour future plan," he said. Tsunoda said his team were working on new ways to spotpatterns of multiple variations in the gene code. "In the future, we would be able to find (a) huge numberof variations in individual genomes that should be related tomany diseases," he said.PTI
