OMIA 001181-9796 : Atrial fibrillation in Equus caballus

In other species: dog

Possibly relevant human trait(s) and/or gene(s) (MIM number): 194200 (trait)

Mendelian trait/disorder: no

Mode of inheritance: Multifactorial

Considered a defect: yes

Key variant known: no

Inheritance: Physick-Sheard et al. (2014) concluded that atrial fibrillation (AF) in Standardbreds is multifactorial and reported that "Heritability of AF on the underlying scale (h²(u)) was estimated at 29.6 ± 3.9% and on the observed binomial scale (h²(o)), at 9.6%."
