Select a complex disease and review the methodology that has been used to identify a susceptibility locus. Since many loci have been mapped for a given disease it is recommended that you select a single gene and review the methodology and evidence for its contribution to the disease.
Your discussion should include:
i. Consideration of the characteristics of the cohort of samples used for genetic analysis, e.g. family studies, ethnicity, disease phenotype, controls etc.;
ii. Discussion of mapping methodology linkage analysis, LOD score interpretation; selection of suitable markers, etc.;
iii. Fine mapping of the locus, and where possible identification of the disease allele;
iv. Other supporting evidence;
v. A brief assessment of further work that could provide more evidence linking the gene to the disease.
