Identification of a gene responsible for light fur pigmentation in the Norway rat
Czech Republic (IFMSA CZ) - Charles University, 1st Medical Faculty, Prague
Institute of Biology and Medical Genetics, First Faculty of Medicine, Charles University in Prague
prof. Ondřej Šeda, M.D., Ph.D
assoc. prof. Frantisek Liska, M.D., Ph.D.
Type of Research Project
- Basic science
What is the background of the project?
A mutation causing light fur pigmentation with normal eye pigmentation ("diluted") was described in the rat decades ago. We set out to identify the molecular basis of the phenotype. Preliminary results of linkage mapping indicated that the diluted gene is localized in proximity of Tyrosinase locus on chromosome 1. What is the aim of the project? 1) To construct a fine linkage map of the locus to determine the exact location of the mutant gene. This can confirm Tyrosinase as the candidate gene. 2) If Tyrosinase is confirmed, test the gene for mutations in coding sequence and differential expression in the diluted skin compared to wild-type. What techniques and methods will be used? polymerase chain reaction (PCR), RT-PCR, real-time RT-PCR, gel electrophoresis
What is the aim of the project?
What techniques and methods are used?
