More than 50,000 SNPs
GeneSeek ® Genomic Profiler Porcine
• Includes approximately 51,000 SNPs with a mean gap of 62 kb
• Higher density marker placement at the telomeric region of the chromosome for increased imputation accuracy
• 33k SNP overlap with PorcineSNP60k
• Imputation accuracy greater than 99%
• Includes disease and performance trait markers
The Next Generation of Porcine Genotyping
Developed in collaboration with corporate and academic scientists, the second generation GeneSeek Genomic Profiler (GGP) for Porcine is built on the foundation of the most globally utilized porcine arrays ever developed. The GGP Porcine array features more than 51,000 SNPs specifically chosen for optimal chromosomal spacing and high minor allele frequency values for use in most commercial breeding lines.
The GGP Porcine array also includes several genetic markers that may directly impact disease and performance traits:
• Porcine Stress Syndrome (HAL)
• Rendement napole (RN)
• Resistance marker to E. coli (F4 ab/ac)
• PRRS tolerance marker (WUR100000125)
• SNPs that have been demonstrated to have an impact on:
Feed Intake
Conversion/Weight Gain
Lean Growth/Fat Content
Meat Quality

The GGP Porcine array provides a very robust solution for imputation to higher density arrays such as the GGP Porcine HD (80k) array. The average imputation accuracy is 99.4% across all chromosomes.
The GGP Porcine array has been validated in many economically important pig breeds. In addition to spacing, SNPs were selected for high MAF values.
