The Portuguese Water Dog Foundation will contribute $9,400 for Whole Genome Sequencing (WGS) on 4 different dogs [2 affected, 1 carriers, and 1 homozygous normal]. Samples will be tested at the WGS platform at the University of Bern, Switzerland. Dr. Aguirre’s eye lab is part of a consortium at Bern where they have WGS on 465 different dogs (at this point, none are PWDs). Bern will provide the initial filtering and data analysis, allowing Dr. Aguirre’s team to focus their analysis and to analyze the approximately 498 predicted genes in the interval in an expedited manner.
Although this proposal focuses strictly on non-prcd form of PRA, the results of the WGS studies will be critically important to other diseases of importance to PWD, for example microphthalmia/multiple congenital ocular anomalies (aka “puppy eye syndrome”) and possibly other diseases that rely on Genome Wide Association Studies (GWAS) to identify the genomic region of interest.
Any study using GWAS to map a disease interval will, much sooner than later, need high quality genomic sequence formation for the region. This comes from having access to as many different dogs/breeds as possible as well as having specific sequence information for the breed of interest from unaffected animals that can be used as disease controls. As the sequence information generated from this project will be publicly available, this resource will complement and inform research work being done on microphthalmia/multiple congenital ocular anomalies disorder as well as other diseases.
