OMIA:002268-10141 : Vitamin C deficiency in Cavia porcellus (domestic guinea pig) |
In other species: pig
Categories: Homeostasis / metabolism phene
Possibly relevant human trait(s) and/or gene(s) (MIM number): 240400 (trait)
Links to MONDO diseases: No links.
Mendelian trait/disorder: yes
Considered a defect: no
Key variant known: no
Species-specific name: Guinea pigs are unable to synthesize L-ascorbic acid; thus they require vitamin C in their diet to prevent scurvy (Burns et al., 1956).
Molecular basis: Nishikimi et al. (1992): "the guinea pig homologue of the L-gulono-gamma-lactone oxidase gene exists as a pseudogene that randomly accumulated a large number of mutations without functional constraint since the gene ceased to be active during evolution."
Genetic engineering:
Unknown
Have human generated variants been created, e.g. through genetic engineering and gene editing
