Abnormal dental enamel of Klk4tm1.1Jpsi/Klk4tm1.1Jpsi incisors

skeleton
• the erupted portion of mandibular incisors are chalky white unlike in wild-type mice
• the enamel of all teeth tends to fracture at point of contact with opposing dentition unlike in wild-type mice
• enamel strength is reduced compared to in wild-type mice
• enamel abrades rapidly following weaning despite a soft diet

mortality/aging
• mice often fail to survive to maturity
• however, mice exhibit normal survival when weaning is extended and mice are fed a soft diet

craniofacial
• the erupted portion of mandibular incisors are chalky white unlike in wild-type mice
• the enamel of all teeth tends to fracture at point of contact with opposing dentition unlike in wild-type mice
• enamel strength is reduced compared to in wild-type mice
• enamel abrades rapidly following weaning despite a soft diet

growth/size/body
• the erupted portion of mandibular incisors are chalky white unlike in wild-type mice
• the enamel of all teeth tends to fracture at point of contact with opposing dentition unlike in wild-type mice
• enamel strength is reduced compared to in wild-type mice
• enamel abrades rapidly following weaning despite a soft diet
• mice exhibit delayed growth
• however, on a soft diet mice eventually achieve a normal adult body weight

homeostasis/metabolism
N
• mice exhibit normal serum levels of calcium, phosphate, magnesium, alanine aminotransferase, and total protein
