Since 1995 the Antczak laboratory has been a major participant in the international collaboration of the Horse Genome Project. This consortium of over 20 laboratories from more than a dozen countries has collaborated to produce various genetic and physical maps of the horse genome, culminating in the whole genome sequence. This enormous research effort has been supported by many funding organizations, including the Havemeyer Foundation, the Zweig Fund, the Morris Animal Foundation, and the US National Institutes of Health.

Two Thoroughbred horses in the Baker Institute’s experimental herd were selected as DNA donors for the equine Bacterial Artificial Chromosome (BAC) library and the genome sequence.  The information from the genome sequence has been used to develop whole genome-scale Single Nucleotide Polymorphism (SNP) assays and other resources for investigations of gene function in the horse.  Using these resources, Dr. Antczak and Dr. Samantha Brooks, then of the Department of Animal Science at Cornell, identified the causative mutation of the lethal inherited disease of Arabian horses known as Lavender Foal Syndrome because of the distinctive coat color of affected animals. A molecular diagnostic test was developed that allows breeders to avoid stallion and mare mating pairs that could result in affected offspring. The Antczak lab is using resources of the Horse Genome Project in several current projects.
