pigmentation
• white coat color, however eyes are black
• no melanocytes are seen in the hair follicles

embryo
• in neural tube cultures, melanoblasts are unable to migrate out from the neural tube
• decrease in the number of melanoblasts between E12.5 and E13.5, with absence of melanoblasts in the trunk region at E13.5
• increase in melanoblast apoptosis at E12.5
