title: Cleft palate susceptibility maps in two H-2 subregions, H-2K to I-B and G to H-2D.
abstract: Data presented here defines the map of H-2 associated genes which affect the glucocorticoid-induced cleft palate frequency to the regions H-2K to I-B and G to H-2D. This was done by observing in four congenic strains the frequency of cleft palate induced by 160 mg/kg of dexamethasone administered to pregnant females on day 12 of gestation. The strains used were B10.A/Sg.Sn, C57BL/10Sn, B10.A (5R)/SgSn and B10.A(18R)/Sg. Additionally the cleft palate frequency was observed in a large number of litters from saline-treated pregnant females. The cleft palate frequency in this control was very low and the rank of strains was the same as for the glucocorticoid-induced cleft-palate frequency. This observation suggests that the induced cleft palate frequency reflects the spontaneous occurrence of isolated cleft palate in these strains.
