• Allelic Composition: Mmut^em2Cpv/Mmut^em2Cpv
• Genetic Background: involves: 129S/SvEv * C57BL/6 * FVB/N

• ♀: phenotype observed in females
• ♂: phenotype observed in males
• N: normal phenotype

mortality/aging

mortality/aging ( J:332892 )

N • no differences in survival are seen at 111 days, indicating no disease-related mortality

growth/size/body

postnatal growth retardation ( J:332892 )

• mice show retarded growth during the first 4 months of life

• treatment with an adeno-associated viral gene therapy expressing human MMUT (AAV-MMUT) increases body weight by an average of 45% within one week of treatment to a size not significantly different from heterozygotes

homeostasis/metabolism

increased circulating methylmalonic acid level ( J:332892 )

• plasma methylmalonic acid concentrations are elevated

• gene therapy treatment with AAV-MMUT decreases plasma methylmalonic acid concentrations by over 75% 3 weeks after treatment
