Direct determination of haplotypes from single DNA molecules

Nat Methods. 2009 Mar;6(3):199-201. doi: 10.1038/nmeth.1301. Epub 2009 Feb 8.

Abstract

Determining the long-range haplotypes in a diploid individual is a major technical challenge. Here we report a method of molecular haplotyping by directly imaging multiple polymorphic sites on individual human DNA molecules simultaneously. We demonstrate the utility of this technology by accurately determining the haplotypes consisting of up to 16 single-nucleotide polymorphisms in genomic regions up to 50 kilobases.
