We subsequently exploited linkage disequilibrium to refine the map position of this QTL to a 3-cM chromosome interval bounded by microsatellite markers BULGE13and BULGE09. We herein report the positional candidate cloning of this QTL, involving (1) the construction of a BAC contig spanning the corresponding marker interval, (2) the demonstration that a very strong candidate gene, acylCoA:diacylglycerol acyltransferase (DGAT1), maps to that contig, and (3) the identification of a nonconservative K232A substitution in the DGAT1 gene with a major effect on milk fat content and other milk characteristics.[The sequence data described in this paper have been submitted to the GenBank data library under accession number AY065621.]}, URL = {http://genome.cshlp.org/content/12/2/222.abstract}, eprint = {http://genome.cshlp.org/content/12/2/222.full.pdf+html}, journal = {Genome Research} }
