• MGI ID: MGI:2181524
• Synonyms: Flv-s
• Gene: Oas1b Location: Chr5:120950700-120962228 bp, + strand Genetic Position: Chr5, 60.64 cM, cytoband F

Mutation origin

• Strain of Origin: various

Mutation description

• Allele Type: Spontaneous (Null/knockout)
• Mutation: Single point mutation
• Mutation details: This allele confers susceptibility to flavivirus infection. Susceptible mouse strains produce a protein lacking 30% of the C-terminal region due a nucleotide substitution. The C-to-T transition results in a premature stop codon at arginine codon 253 (p.R253*). (J:77001)

Find Mice (IMSR)

• Mouse strains and cell lines available from the International Mouse Strain Resource (IMSR)
• Carrying this Mutation: Mouse Strains: 1 strain available Cell Lines: 0 lines available
• Carrying any Oas1b Mutation: 15 strains or lines available

Notes

The majority of mouse strains carry the susceptibility allele. Only the Det, BSVR, BRVR, CASA/RK, CAST/Ei, and PRI carry the resistance allele. The MOLD/Rk strain carried the allele for minor resistance.
