OMIA 000608-9031 : Loco, congenital in Gallus gallus

In other species: turkey , Japanese quail

Mendelian trait/disorder: yes

Mode of inheritance: Autosomal Recessive Lethal

Considered a defect: yes

Key variant known: no

Species-specific symbol: lo

Inheritance: Knowlton (1929) provided evidence of autosomal recessive inheritance.

Mapping: Okumura et al. (2013) conducted a genome scan with 122 informative miccrosatellites on 88 Rhode Island Red chickens from several generations of families segregation for this disorder. Linkage analysis highlighted just one region near microsatellite MCW0332 on chromosome GGA12. Subsequent homozygosity mapping narrowed the region "to approximately 1.1 Mb, between GGA12_28 and GGA12_30", which contains at least 10 genes.

Breed: Rhode Island Red.
