1. X-linked recessive chondrodysplasia punctata due to a new point mutation of the Arse gene

2. A naturally occurring point mutation Confers broad range tolerance to herbicides that target acetolactate synthase J

3. And what they find is a single-point mutation in a gene responsible for controlling programmed cell death.

4. Alymphoplasia (Aly) mice, which carry a point mutation in the nuclear factor κB–inducing kinase (NIK) gene, are characterized by the systemic absence of lymph nodes and Peyer's patches, disorganized splenic and thymic architectures, and immunodeficiency.Another unique feature of Aly/Aly mice is that their peritoneal cavity contains more B1 cells than normal and Aly/+ mice.
