OMIA:002418-9940 : Mycotoxicosis, susceptibility/resistance to in Ovis aries (sheep)

Categories: Nervous system phene

Links to MONDO diseases: No links.

Mendelian trait/disorder: no

Mode of inheritance: Multifactorial

Considered a defect: yes

Key variant known: no

Species-specific name: Ryegrass staggers

Species-specific description: Ryegrass staggers is caused by the ingestion of perennial ryegrass (Lolium perenne L.) containing a fungal endophyte (Neotyphodium lolii). The fungal endophyte produces a tremorgenic toxin, lolitrem B.

Genetic engineering: Unknown
Have human generated variants been created, e.g. through genetic engineering and gene editing
