All three teams found sections
of DNA —
haplotypes — that differed and ultimately pinpointed a single - letter difference that changed the amino - acid content
of complement factor H. HapMap researchers say that refining the
map further will speed up such discoveries, and they plan to release a new version this month that will include 4 million single - nucleotide variants.
After months
of passing the hat among countries and private companies, the U.S. National Institutes
of Health (NIH) announced today that it has garnered the $ 100 million the 3 - year effort to construct a so - called
haplotype map is likely to cost.
Efforts include the National Institutes
of Health Diabetes Genome Anatomy Project and another NIH - sponsored venture, the International HapMap Project, which is creating a
map of regions in the human genome called
haplotypes, where the underlying DNA influences common diseases like diabetes.
In response, Page and colleagues devised what is known as SHIMS (single -
haplotype iterative
mapping and sequencing) to establish a definitive reference DNA sequence
of the Y chromosome.
To study natural selection, the team combed the International
Haplotype Map for long stretches
of DNA flanked by a single nucleotide polymorphism (SNP, or «snip»)-- that is, an altered base, or «letter,» in the genetic alphabet.
Their content is optimized for genetic
mapping in the Collaborative Cross and Diveristy Outbred populations; for discriminating
haplotypes from common laboratory strains and substrains; and for evaluating the ancestry
of wild - caught mice.
The maize reference genome and the
haplotype map are published online today ahead
of print in the journal Science, in addition to a supplementary poster on the maize genome placing the plant and the sequencing project in historical and cultural perspective.
The HapMap, a shorthand for
haplotype map, gauges diversity in the maize genome by comparing 27 distinct genetic lines
of the plant with the reference version.
As a demonstration, we use the gPBWT to quickly count the number
of haplotypes consistent with random walks in a genome graph, and with the paths taken by
mapped reads; results suggest that
haplotype consistency information can be practically incorporated into graph - based read mappers.
For efficient
mapping of these mutants and mutation identification, we devised a new
mapping strategy based on identification
of mutant - specific
haplotypes.
