| Summary |
3 genotypes
|
|
|
| ♀ | phenotype observed in females |
| ♂ | phenotype observed in males |
| N | normal phenotype |
|
• a few mice survive beyond weaning but mice rarely survive past 6 months of age
|
|
• unlike homozygous mice not carrying the transgene which all die by P15, most mice carrying the transgene die between P17 and P21
|
|
|
| ♀ | phenotype observed in females |
| ♂ | phenotype observed in males |
| N | normal phenotype |
|
• substantial improvement in life span compared to heterozygous mice not carrying the transgene; 50% survival at 6 months of age compared to 25%

| N | normal phenotype |
|
• decreased threshold for kainic acid induced seizures compared to control transgenic lines
|
|
• the ratio of sodium current densities in bipolar versus pyramidal neurons is reduced and the sodium current density in bipolar cells is reduced compared to controls
• sodium channels appear to recover more slowly from inactivation and current through the channels decreases during a series of depolarizations in bipolar neurons
• in pyramidal neurons a negative shift is seen in the voltage dependence of inactivation
|
|
• decreased threshold for kainic acid induced seizures compared to control transgenic lines
