Additional file 5 of Genome data uncover four synergistic key regulators for extremely small body size in horses

Functional classification of genes. Variants identified in ROH regions in the two Miniature Shetland ponies and one standard sized Shetland pony, which were estimated to be deleterious (SIFT prediction) were investigated for their genomic positions in genes. In addition, variants, which showed an exclusively homozygous mutant genotype in all three Shetland ponies, were added to the analysis. Human orthologue genes were functionally classified using DAVID Functional Annotation Tool. (XLSX 23 kb)
