Abstract:
Members of the caspase family can be important for apoptosis or inflammation, but the role of caspase-12 (CASP12 or CSP12) is unclear. Although most humans lack a functional caspase-12, the Csp 12-L variant, previously found only among people of African descent, produces a full-length proenzyme and increases the risk of sepsis. In this study, Csp 12-L allele frequency ranged from 3.6% to 60.7% among populations from sub-Saharan Africa and was also present at low frequency among North African, Middle Eastern, and South Asian populations.

Lethal Alleles
Lucien Cuénot discovered lethal alleles in 1905 while studying the inheritance of coat color in mice. The agouti gene is responsible for the color of the coat in mice. This gene codes for an agouti-signaling protein, which is responsible for melanin distribution in mammals. The wild-type allele gives rise to gray-brown coat color in mice, while the mutant allele gives rise to yellow coat color. In addition to coat color, the agouti gene is associated with the yellow...
