cx2

• Allelic Composition: Car14^tm1Sly/Car14^tm1Sly; Car4^tm1Sly/Car4^tm1Sly
• Genetic Background: involves: 129S1/Sv * C57BL/6

mortality/aging

postnatal lethality ( J:103742 )

• reduced survival of both male and female with a greater deficiency of females by weaning

• homozygous mice were only 38% of the number expected from Mendelian ratio

• the sex ratio was skewed in that 74% of the homozygotes were male

• male double homozygous mice that survived to weaning appeared healthy, grew, and were fertile

• many of female double homozygous mice died early

reproductive system

female infertility ( J:103742 )

♀ • few female double homozygous mice that survived to weaning were infertile

growth/size/body

decreased body size ( J:103742 )

• both males and females double homozygous mice that survived to weaning were significantly smaller than wild-type

homeostasis/metabolism

abnormal pH regulation ( J:103742 )

• blocked buffering of the alkaline pH shifts as effective as the CA inhibitor, benzolamide, that accompany neuronal activity in hippocampal slices
