phenotype observed in males EuPh Europhenome
N normal phenotype
       
mortality/aging
• the proportion of homozygotes is decreased to 19.1% and data suggest death late in gestation

vision/eye
• at 2-3 months of age a slight reduction in the outer nuclear layer and some cell nuclei in the subretinal space were seen
• at 8 months of age the outer nuclear layer is completely degenerated and no remnants of the inner or outer segments are seen

growth/size
• at weaning homozygotes weigh significantly less than wild-type or heterozygous littermates
• by 28 weeks of age homozygotes weigh significantly more than wild-type or heterozygous littermates and the weight difference is greater in females than in males

cardiovascular system
• diastolic, systolic, and mean blood pressure are increased with mean arterial pressure increased on average by 12 mmHg

behavior/neurological
• homozygotes are more docile during handling and in 72% and 76% of trials were submissive to wild-type and heterozygous mice, respectively
• 24 hour telemetry indicates a significant decrease in activity; however, no significant differences in muscle or motor neuron function dependent behaviors are seen
• females are less vocal during handling

homeostasis/metabolism

limbs/digits/tail
N
• no polydactyly or other notable limb malformations are seen (J:99276)

reproductive system
• spermatozoa lack flagella but have normally formed heads and cilia on epithelial cells form normally (J:99276)
(J:99276)

taste/olfaction
• decreased olfactory ability suggested by a decreased ability to find hidden food

cellular
• spermatozoa lack flagella but have normally formed heads and cilia on epithelial cells form normally (J:99276)
