OMIA:001258-9823 : Obesity in Sus scrofa (pig)

In other species: crab-eating macaque , dog , domestic cat , horse , rabbit

Categories: Adipose tissue phene

Links to possible relevant human trait(s) and/or gene(s) in OMIM: 164160 (gene) , 614962 (trait)

Mendelian trait/disorder: unknown

Disease-related: yes

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 ..." This phene includes references to studies involving genetically modified organisms (GMO).

Genetic engineering: Yes - in addition to the occurrence of natural variants, variants have been created artificially, e.g. by genetic engineering or gene editing
Have human generated variants been created, e.g. through genetic engineering and gene editing
