Comparative analysis of whole exome sequencing kits for the canine genome.

Abstract

ObjectivesAs the public's interest in companion dogs grows, health issues in these animals are also emerging, necessitating the optimization of whole exome sequencing (WES) as a valuable method for disease prediction. While WES targeting the human genome is well established, WES targeting the canine genome is understudied, and there is a need to find effective analysis kits.MethodsWe compared and analyzed the performance of three WES kits from Twist and Agilent using the canine genome as the target to perform genetic analysis of canine diseases effectively. The levels of total reads, the duplication rate, and variant calling in canine genomic DNA samples from seven healthy dogs (three beagles, one bichon fry, one maltese, one welsh corgi, and one mixed breed) without any interventions were examined through WES via Twist and Agilent kits.ResultsWe found that while Twist had the lowest total read number, the number of reads in the SSXT series was significantly (PConclusionThe most important performance of the kit, the number of variants detected, was 48,302 for Twist and 130,506 for SSXT (O/N). On the basis of the performance comparison results, SSXT (O/N) was found to have the best performance.
