N normal phenotype
mortality/aging
• 1 surviving mice died shortly after weaning
• mice supplemented with inositol die of unknown causes before wild-type mice
• all but one mice died prior to birth
• however, supplementation with inositol increases survival to weaning

behavior/neurological
N
• mice supplemented with inositol exhibit normal performance on a rotarod
• in mice supplemented with inositol in dark- and light-box, forced-swim, Y-maze tests, and fear-conditioning test
• in males in a an open field
• delayed onset and offset of free-running under constant dark in mice supplemented with inositol
• in older mice supplemented with inositol when removed from their home cages and placed on the floor

• mice supplemented with inositol exhibit normal craniofacial development
• at E14.5, but not E10.5
• in one mouse
