Genotyping of non-human primates indicates that the 577X null mutation has likely arisen in humans.

The effects of the null mutation are more severe than the effects of the C282Y mutation.

A null mutation of Hhex results in a failure to form the liver bud and embryonic lethality.

Mice homozygous for an Ikaros null mutation display distinct defects in the development of fetal and adult lymphocytes.

We investigated the in vivo function of GABP by generating a null mutation in the murine Gabpalpha gene.

To test this model, we cloned the gene for the S. cerevisiae guanosine diphosphatase and constructed a null mutation.

Phenotypic comparison of this null mutation with a severe dominant-negative Ikaros mutation identifies molecular redundancy in the postnatal hemolymphoid system.
