Cranial cruciate ligament rupture (CCLR) is the most common cause of pelvic limb lameness in dogs. To investigate the genetic basis of canine CCLR, we conducted a genome-wide association study using a canine SNP array in Newfoundland pedigree dogs with and without CCLR (n = 96). We identified three main chromosomal regions of CCLR association (on chromosomes 1, 3 and 33). Each of these regions was confirmed by Sequenom genotyping in a further cohort of Newfoundlands (n = 271). The results, particularly SNPs identified in the SORCS2 and SEMA5B genes, suggest that there may be neurological pathways involved in susceptibility to canine CCLR.
颅交叉韧带破裂(CCLR)是犬只后肢跛行最常见的原因。为了研究犬类CCLR的遗传基础,我们使用犬类单核苷酸多态性(SNP)芯片,对有或没有CCLR的纽芬兰纯种犬(n = 96)进行了全基因组关联研究。我们确定了与CCLR相关的三个主要染色体区域(位于第1、3和33号染色体上)。在另一组纽芬兰犬(n = 271)中,通过Sequenom基因分型对这些区域进行了逐一验证。研究结果,特别是在SORCS2和SEMA5B基因中鉴定出的SNP,表明犬类CCLR易感性可能涉及神经通路。
