Identity: CRISPR-Cas9 editing with or without homology dependent repair in heat-susceptible beef breeds to introduce mutations into at least one copy of the PRLR gene of Bos taurus chromosome 20 (NC_037347.1). The intended mutations generate a premature stop codon in the coding sequence resulting in a truncated PRLR protein and a SLICK coat phenotype.
Claim: Mutations causing PRLR protein truncation at or between amino acids 433 to 497 produce a SLICK coat phenotype that is reported to be linked to increased thermotolerance in Bos taurus species raised in sub-tropical environments.
Product Use: Founder animals are intended for production and sale of seed stock and/or embryos to enable the establishment of PRLR-SLICK thermotolerant beef herds that will be used as a food source. Due to the specific process used to produce these animals, they may have 2 or more genetically different sets of cells, and as a result the PRLR-SLICK thermotolerant phenotype may not be inherited by all first generation progeny.
