growth/size/body
• affected mice appear smaller than their normal littermates

homeostasis/metabolism
• histologic examination reveals generalized epidermal edema

integument
• histologic examination reveals generalized epidermal edema
• hair of homozygous mutant mice is abnormally prone to breakage; consequentially, the hair coat of homozygous mutant mice is very short, particularly on the extremities, i.e., ears, tail, muzzle and limbs to the hock or elbow, and on the ventrum
• the dorsal fur looks more normal than that elsewhere, but appears to lack guard hairs
• above the base of the hair follicle is an area that stains brightly orange/pink, suggesting premature cornification of the hair shaft and inner root sheath
• above the base of the hair follicle is an area that stains brightly orange/pink, suggesting premature cornification of the hair shaft and inner root sheath
• the bases of affected hair follicles have an "onion bulb" appearance
• skin of affected mice may be slightly hyperemic or reddened
