Nonneuronal expression of the GABA(A) beta3 subunit gene is required for normal palate development in mice.

Abstract excerpt

Cleft palate is one of the most common birth defects in humans, in which both genetic and environmental factors are involved. In mice, loss of the GABA(A) receptor beta3 subunit gene (Gabrb3) or the targeted mutagenesis of the GABA synthetic enzyme (Gad1) leads to cleft palate. These observations indicate that a GABAergic system is important in normal palate development. To determine what cell types, neuronal or...
