Summary of the indels found in the targeted sequencing.

Only variants that are homozygous for a rare allele in all affected dogs and not homozygous in controls were considered to perfectly segregate. Hom: Nb Homozygous variants; HTZ: Nb Heterozygous variants.仅将同时满足以下条件的变异位点纳入分析：在全部患病犬中均为罕见等位基因（rare allele）纯合状态，且在对照组犬中不呈纯合状态。此类变异被认为符合完美分离规律。 Hom：纯合变异数量（Number of Homozygous variants）；HTZ：杂合变异数量（Number of Heterozygous variants）。
