ASIP and deafness: Similarly, neither the second region of the genome associated with red coat colour in dog breeds, the dominantly acting Ay allele at the Agouti locus (ASIP) on CFA24 [29], or the third region containing the K locus on CFA16, which may also cause a red coat indistinguishable from that caused by Mc1r recessive red allele [34], are implicated in red coat and deafness in the ASCD.
