Summary A genome‐wide association scan for loci affecting withers height was conducted in 782 G erman W armblood stallions, which were genotyped using the I llumina E quine SNP 50 B ead C hip. A principal components approach was applied to correct for population structure. The analysis revealed a single major QTL on ECA 3 explaining ~18 per cent of the phenotypic variance, which is in concordance with recent reports from other horse populations. The LCORL / NCAPG locus represents a strong candidate gene for this QTL . This locus is among a small number that have consistently been identified to influence human height in several large meta‐analyses. Furthermore, a mutation within the NCAPG gene was found to affect growth and body frame size in cattle. Together with the results of this study in G erman W armbloods, these findings strongly indicate LCORL / NCAPG as a candidate locus for withers height in horses. Further studies are, however, needed to confirm this.
