Candidate Genes
An initial genome scan was performed with 186 (PERA/EiJ x DBA/2J) F2 animals using 98 SSLP markers at a resolution of 17.1 cM. Parental strain PERA/EiJ is resistant to gallstone formation after 8 weeks on a high fat diet where as parental strain DBA/2J is susceptible. Animals were fed a high fat diet starting at 6-8 weeks of age. After candidate loci were identified an addition set of 93 F2 animals were genotyped at selected regions. This dataset was combined with a previous PERA/EiJ x I/LnJ dataset for additional analysis. Mapping and Phenotype information for this QTL, its variants and associated markersJ:84582The Authors provided QTL analysis between the gallstone-susceptible wild-derived inbred strain PERA/Ei (PERA), and a resistant inbred strain, I/LnJ (I), and detected three new Lith loci which were named Lith7, Lith8 and Lith9. Lith7 mapped to mouse Chromosome10 and was associated with D10Mit12. Lith8 mapped to mouse Chromosome 4 and was associated with D4Mit12. Lth9 mapped to mouse Chromosome 17 and was associated with Abcg5. In addition to the mapping the authors provided the physical chemical and molecular basis of gallstone formation in strain PERA as compared to strain I. The analysis allowed for the identification of candidate genes underlying the QTLs. Nr1h4 underlies Lith7, and the genes encoding the canalicular cholesterol half-transporters Abcg5 and Abcg8underlie Lith9. Whereas Nr0b2 was a suggested candidate for Lith8 |
