Interestingly, two of the identified genes are, instead, associated with coat colour: USH2A is related to roan and ticked colour in dogs [27], whereas LYST is known to determine beige, aleutian, and diluted colour in mice, minks, and bovines, respectively [28,29,30], and also to cause Chediak–Higashi syndrome in several species [28,31,32]. Here, USH2A is linked to Chédiak-Higashi syndrome.
