Mendelian trait/disorder: unknown

Considered a defect: yes

Year key variant first reported: 2013

Molecular basis: Being well aware of the role of mutations in FMO3/FMO6P being causal for this disorder in cattle (OMIA 001360-9913) and chickens (OMIA 001360-9031), Mo et al. (2013) cloned and sequenced the quail FMO3 gene, and identified "a nonsense mutation ([c.992C>T]; Q319X) which was significantly associated with the elevated TMA content in quail egg yolks. Genotype TT at Q319X mutation loci was sensitive to choline. With addition of choline in the feed, the quails with homozygote TT at the Q319X mutation loci laid fish-odour eggs, indicating an interaction between genotype and diet. The results indicated that Q319X mutation was associated with the fishy off-flavor in quail eggs."
