Abstract:
Apolipoprotein A5 is a recently discovered apolipoprotein involved primarily in triglyceride metabolism. Several single-nucleotide polymorphisms have been investigated since the initial report. The -1131T>C polymorphism has been associated with higher triglyceride levels and a decreased high-density lipoprotein cholesterol as well as with susceptibility to coronary heart disease. However, no study has so far emphasized on the association of a dietary intervention with apolipoprotein A5 polymorphisms. In a group of 606 hyperlipaemic and overweight men, we investigated how a short-term fat restriction affects lipid traits and body mass index (BMI) in wildtype and carriers of the -1131T>C polymorphism. Our result was that the reduction of BMI was significantly higher in C allele carriers (p=0.0021). Since the -1131T>C polymorphism predisposes to coronary heart disease, a restriction diet is an important therapeutic approach in -1131T>C carriers.

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...
