CNVs randomly selected based on incidence and size validated through qPCR. CNVR identification, chromosome (ECA), start and end position (in bp) and size of the CNVs in the investigated Friesians horse sample is presented, including information on whether the CNV concerned a private (present in 1 horse) or shared (present in 2 horses; the exact same breakpoints were observed) CNV. The designed primers, state of the CNV and results of the qPCR are given. (DOCX 14 kb
