In bovines, coding variants within the microphthalmia-associated transcription factor (MITF) gene cause distinct white coat color phenotypes (Petersen et al. 2023; OMIA 001401-9913), often associated with ocular malformations such as microphthalmia (Wiedemar and Drögemüller 2014; OMIA 001931-9913), bilateral hearing loss, heterochromia iridis, and glass-eyed albino phenotype (Philipp et al. 2011; Bourneuf et al. 2017; OMIA 001680-9913). This evidence concerns the gene MITF and microphthalmia.
