OMIA 001956-9031 : Resistance to avian sarcoma and leukosis viruses, subgroup J in Gallus gallus

Mendelian trait/disorder: yes

Mode of inheritance: Autosomal Recessive

Considered a defect: unknown

Key variant known: yes

Year key variant first reported: 2020

Species-specific description: Chai and bates (2006) identified the receptor for subgroup J viruses as being the Na+/H+ exchanger type 1 (chNHE1).

Molecular basis: Using "precise CRISPR/Cas9 gene editing", Koslová et al. (2020) deleted the triplet for the critical receptor amino acid (W38) in the chNHE1 gene that encodes functional receptor for subgroup J leukosis virus, creating ΔW38. The authors reported that "The resistance to ALV-J was examined both in vitro and in vivo, and the ΔW38 homozygous chickens tested ALV-J-resistant, in contrast to ΔW38 heterozygotes and wild-type birds, which were ALV-J-susceptible. Deletion of W38 did not manifest any visible side effect."
