hematopoietic system
• platelet ADP levels are much lower than in C57BL/6J controls
• platelet ATP levels are much lower than in C57BL/6J controls
• fewer platelet dense granules than normal
• less than 7% of normal levels of platelet serotonin (J:7327)
• platelet serotonin level is also lower than that of control when fed an atherogenic diet (J:29748)

homeostasis/metabolism
• less than 7% of normal levels of platelet serotonin (J:7327)
• platelet serotonin level is also lower than that of control when fed an atherogenic diet (J:29748)
• bleed time averaging over 15 minutes after tail nick is much greater than the 3.8 minutes for C57BL/6J controls

cardiovascular system
• on an atherogenic diet homozygotes develop fewer aortic lesions and smaller lesions than C57BL/6J controls
• 60% of homozygotes survive to 48 weeks of age on an atherogenic diet, when no C57BL/6J controls survive, and, although there are significant atherosclerotic lesions in these 48 week old homozygotes, the lesions are smaller than those in 39 week old C57BL/6J controls fed the atherogenic diet

pigmentation
• the black pigment in the coat is reduced on this background and is described as sepia, reddish-brown or slate-black
• yellow coat pigment in hair behind the ears, surrounding the mammae, and in the perineum is slightly diluted
• at birth the iris pigment ring is lacking and adults have ruby colored eyes (J:13122)
• electron microscopy shows reduced numbers of melanosomes in the retinal pigment epithelium, those that are found have abnormal morphology including multilamellar or granular inclusions, and choroidal melanosomes are also often misshapen and less dense than normal and tend to be clumped within multimelanosomal bodies (J:81444)
• the number of melanocytes in the retina, ear skin, Harderian gland, are greatly reduced
• eyes are unpigmented at birth but later, when opened, are a dark ruby color
