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.
