Summary of the SNPs 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. Nb SNPs: Number of SNPs; Hom: Nb Homozygous variants; HTZ: Nb Heterozygous variants.仅将在所有患病犬只中呈稀有等位基因纯合状态，且在对照犬只中不呈纯合状态的变异位点，认定为与疾病表型完美共分离的变异。Nb SNPs：单核苷酸多态性（Single Nucleotide Polymorphisms, SNPs）数量；Hom：纯合变异位点数量；HTZ：杂合变异位点数量。
