Heritable pulmonary lobation anomaly in the rat.
A new mutant gene which caused fusion of lung lobes was found in the Wistar rat. The genetic analysis revealed an autosomal recessive inheritance and the mutant gene was named fused pulmonary lobes (gene symbol: fpl). The right lung of the fpl/fpl homozygotes had fused lobes of varying degrees. The fpl/fpl homozygotes were semilethal at the neonatal stage and had externally visible associated malformations such as malocclusion of incisors, eyelid anomalies, and digit abnormalities in the fore- and hindlimbs with different incidences. These traits were considered to be caused by the pleiotropic effects of the fpl gene.
