Mouse lines carrying:
Ostm1om mutation (1 available); any Ostm1 mutation (23 available)
♀ phenotype observed in females
♂ phenotype observed in males
N normal phenotype
mortality/aging
lethality at weaning, incomplete penetrance ( J:195249 )
• however, provision with soft food improves survival
premature death ( J:195249 )
• shortened life span in some mice

skeleton
abnormal incisor morphology ( J:195249 )
• at P14, P21 and P30 to P32, some mice exhibit small or thinner teeth or missing incisors
• most incisors erupt but appear damaged and degenerate within the first month of life
abnormal molar morphology ( J:195249 )
• molars are not regularly aligned
• upper molar 3 appears damaged
• some molars are still covered with bone and an epithelial cell layer
failure of tooth eruption ( J:195249 )
• most molars fail to erupt
abnormal maxilla morphology ( J:195249 )
• rough appearance around the roots of damaged upper incisors
• sclerosis in the maxillary area
abnormal maxillary zygomatic process morphology ( J:195249 )
• the zygomatic process of the maxilla is thicker and continues to be thick halfway into the zygomatic bone compared to in wild-type mice
abnormal long bone morphology ( J:195249 )
• layered appearance
abnormal deltoid tuberosity morphology ( J:195249 )
• increased density and abnormal morphology
abnormal femur morphology ( J:195249 )
• increased density of the diaphyses in female mice
• increased density at the distal epiphysis
abnormal rib morphology ( J:195249 )
• thick proximal ribs 1 through 8, especially on the dorsal parts
decreased bone mineral density ( J:195249 )
• full body, femur or right knee in female mice at 8 and 12 weeks
• in male mice at 8 but not 12 weeks
abnormal compact bone morphology ( J:195249 )
• in the jaw, the compact bone is invaded by blood vessels and has a very irregular structure
abnormal trabecular bone morphology ( J:195249 )
• disorganized in the jaw
osteopetrosis ( J:195249 )
• progressive in female, but not male, mice

craniofacial
abnormal incisor morphology ( J:195249 )
• at P14, P21 and P30 to P32, some mice exhibit small or thinner teeth or missing incisors
• most incisors erupt but appear damaged and degenerate within the first month of life

• rough appearance around the roots of damaged upper incisors
• sclerosis in the maxillary area
abnormal maxillary zygomatic process morphology ( J:195249 )
• the zygomatic process of the maxilla is thicker and continues to be thick halfway into the zygomatic bone compared to in wild-type mice

homeostasis/metabolism
decreased circulating LDL cholesterol level ( J:195249 )
• likely due to poor nutritional status
decreased circulating triglyceride level ( J:195249 )
• likely due to poor nutritional status

growth/size/body
abnormal incisor morphology ( J:195249 )
• at P14, P21 and P30 to P32, some mice exhibit small or thinner teeth or missing incisors
• most incisors erupt but appear damaged and degenerate within the first month of life
short incisors ( J:195249 )
abnormal molar morphology ( J:195249 )
• molars are not regularly aligned
• upper molar 3 appears damaged
• some molars are still covered with bone and an epithelial cell layer
failure of tooth eruption ( J:195249 )
• most molars fail to erupt
decreased lean body mass ( J:195249 )
decreased body size ( J:195249 )
• around time of weaning

adipose tissue

pigmentation
abnormal coat/hair pigmentation ( J:195249 )
• more grey less yellow coat color

hematopoietic system
decreased hemoglobin content ( J:195249 )
• likely due to poor nutritional status
