OMIA:002577-9986 : Lethality, RYR2-related in Oryctolagus cuniculus (rabbit)

Categories: Cardiovascular system phene

Mendelian trait/disorder: yes

Mode of inheritance: Autosomal recessive lethal

Considered a defect: yes

Key variant known: no

Species-specific description: Zheng et al. (2022) "used a constitutive knock-out of RyR2 in rabbits (RyR2-KO) to assess the extent to which a stable decrease in RyR2 expression modulates Ca2+ handling in the heart. We found that homozygous knock-out of RyR2 in rabbits is embryonic lethal. Remarkably, heterozygotes (KO+/-) show ~50% loss of RyR2 protein without developing an overt phenotype at the intact animal and whole heart levels." This study involves genetically modified organisms (GMO).

Genetic engineering: Yes - 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
