Species-specific description: Zhu et al. (2020) used CRISPR/Cas9 technology to knock out the iroquois homeobox 3 (IRX3) gene, which is implicated in human obesity, in Bama minipigs. However, "use of IRX3-/- cells as donor cells for the production of somatic cell-cloned pigs results in a significant decrease in the average live litter size and a significant increase in the average number of stillbirths. Moreover, the birth weight of surviving IRX3-/- somatic cell-cloned pigs is significantly lower, and viability is poor such that all piglets die shortly after birth. ... IRX3 should not be used as a gene editing target to reduce fat content ..."
