mortality/aging
• the majority of mice born fail to feed and die or disappear within 24 hours
• some mice survive to various ages
• small animals die at various ages within a few weeks of birth

behavior/neurological
• mice surviving to at least 2 weeks of age possessed a tremor

growth/size/body
• mice that feed and survive to at least 2 weeks of age, are small

renal/urinary system
• animals test positive for urine glucose from about 4 weeks of age
• urine glucose levels increase with age
• blood glucose and insulin levels are normal
• kidneys abnormalities vary in severity, but appeared grossly abnormal, pale in color and with lumpy surface
• tubular nephritis is seen in mutants that survive beyond one month

vision/eye
• lenses remain undifferentiated even in mice surviving beyond 2 weeks of age

homeostasis/metabolism
• animals test positive for urine glucose from about 4 weeks of age
• urine glucose levels increase with age
• blood glucose and insulin levels are normal

immune system
• tubular nephritis is seen in mutants that survive beyond one month
