Notes

• Experiment
  The inheritance and complexity of the C5-independent genetic control to C. albicans resistance of AKR/J mice was investigated by phenotyping mice from an F2 cross generated between resistant AKR/J and susceptible A/J progenitors, in which all mice were fixed for C5 deficiency.
  
  A total of 158 [A/J x AKR/J]F2 mice were infected with C. albicans blastospores. The kidney fungal burden was determined and used as a quantitative phenotypic measure of susceptibility in linkage analysis. F2 mice were genotyped with a custom panel of 257 informative, polymorphic markers distributed across the genome.
  
  The analysis identified a highly significant linkage on chromosome 11 (LOD=4.59, P<0.01).
  The QTL was named Carg4, Candida albicans resistance gene 4, and mapped to a 70.7-103.8 Mb region with a peak at 98.8 Mb, (peak SNP:rs3661058). Authors list eleven genes as positional candidate genes for Carg4.
  
  A two-dimensional Haley-Knott multiple regression anaylsis revealed that the joint effect of Carg3 and Carg4 increased the LOD score to 11.5, suggesting an additive effect which explains 28% of the phenotypic variance observed.
