Abstract:
This report highlights case of two siblings who developed haemophagocytic lymphohystiocytosis due to distinct genetic abnormalities. Though their presentation was clinically similar, the cases demonstrate that a shared genetic diagnosis among siblings cannot be assumed.

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...
