Together these data show that a genetic deficiency in Gria4, whether reduction (Gria4spkw1 allele) or complete lack (Gria4tm1Dgen allele), is associated with a high frequency of SWD, modeling absence epilepsy.
Spec (whether) Negative_regulation (deficiency) of Gria4 associated with absence epilepsy

The association of Gria4 deficiency with a high rate of SWD is also interesting in view of stargazer mice, which have a similar epileptic phenotype along with other neurological impairments (43,44).
Negative_regulation (deficiency) of Gria4 associated with epilepsy

Furthermore, decrease in transcript levels was accompanied by a significant reduction in the amount of GluR4 protein in HeJ cerebellum compared with control (Fig. 3C)—suggesting that HeJ carries a severely hypomorphic allele of Gria4.
Negative_regulation (reduction) of GluR4 in cerebellum

To confirm the causal relationship between Gria4 deficiency and SWD, we assessed the electroencephalographic phenotype of an independent mutation of Gria4: the Gria4tm1Dgen knockout allele (expression defect data are shown in Figure 3B and C; see Materials and Methods for more details on the origin and nature of Gria4tm1Dgen).
Negative_regulation (deficiency) of Gria4 associated with targeted disruption

Observed backpropagation characteristics such as reduction in spike amplitude and failure of antidromic transmission of APs into dendrites as well as findings on spike initiation sites can be explained by the distribution of low-threshold Nav1.6 and high-threshold Nav1.2 sodium channels in pyramidal cells (Stuart et al., 1997; Yu et al., 2008; Hu et al., 2009).
Negative_regulation (reduction) of spike in dendrites associated with pyramidal cell, sodium channel, nav1.2 and nav1.6
