OMIA:002571-9823 : 5-Hydroxytryptamine deficiency in Sus scrofa (pig)

Categories: Nervous system phene

Links to possible relevant human trait(s) and/or gene(s) in OMIM: 607478 (gene)

Mendelian trait/disorder: yes

Considered a defect: yes

Key variant known: no

Species-specific name: 5-HT deficiency

Species-specific description: Li et al. (2017) used CRISPR/Cas9 technology to create 10 TPH2 targeted piglets. "These Tph2 KO piglets were viable and appeared normal at the birth. However, their central 5-HT levels were dramatically reduced, and their survival and growth rates were impaired before weaning." 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

Breed: Bama Xiang Zhu, China (Pig) (VBO_0012741).
Breeds in which the phene has been documented. (If a likely causal variant has been documented for the phene, see the variant table breeds in which the variant has been reported).
