A genome‐wide significant association on chromosome 15 for congenital entropion in Swiss White Alpine sheep

7 monthes ago   |   By Animal Genetics

Summary
Entropion is a known congenital disorder in sheep presumed to be heritable but no causative genetic variant has been reported. Affected lambs show a variable inward rolling of the lower eyelids leading to blindness in severe cases. In Switzerland, the Swiss White Alpine breed showed a significantly higher prevalence for entropion than other breeds. A GWAS using 150 SWA sheep , based on 600k SNP data, revealed a genome‐wide significant signal on chromosome 15. The 0.2 Mb associated region contains functional candidate genes, SMTNL1 and CTNND1. Pathogenic variants in human CTNND1...

Genome‐wide association study of body weight and conformation traits in neonatal sheep

7 monthes ago   |   By Animal Genetics

Summary
Sheep, an important source of meat, dairy products and wool, play an essential part in the global agricultural economy. Body weight and body conformation are key traits in the sheep industry; however, their underlying genetic mechanisms are poorly understood. In this study, a GWAS was implemented to identify promising genes possibly linked to birth weight and body conformation traits in neonatal sheep, using a high‐throughput chip. After quality control, 277 individuals and 518 203 variants were analyzed using gemma software in a mixed linear model. A total of 48 genome‐wide...
