The aetiology of spina bifida involves genetic and environmental factors, which may be why major genes contributing to pathogenesis have not been identified. Here we report that undulated-Patch double-mutant mice have a phenotype reminiscent of an extreme form of spina bifida occulta in humans. This unexpected phenotype in double-mutant but not single-mutant mice shows that novel congenital anomalies such as spina bifida can result from interaction between products of independently segregating loci. This example of digenic inheritance may explain the often sporadic nature of spina bifida in humans. [less ▲]
