  • focused on single nucleotide rare variants

  • links to > 10 association tests at the gene or genomic area level, with correction or subpopulation and covariates

  • quite of an effort to understand and follow up on all the methods referenced
  • briefly mentions pathway analysis (ref to Autism Nature paper)

• An evaluation of statistical approaches to rare variant analysis in genetic association studies.

Cancer Mutations

• Patient-oriented gene set analysis for cancer mutation data
  Boca SM, Kinzler K, Velculescu VE, Vogelstein B, Parmigiani G.
  Genome Biol. 2010 Nov 23;11(11):R112.

  • It's basically the same idea applied to cancer instead of autism.
  • However, lacking the control patients (since cancer is high mutation frequency, that would not make sense), they have to define the null hypothesis using randomly placed mutations.
  • What they call "exclusivity principle" is what I usually call the "OR combination logic" (i.e. at least one perturbed gene for the pathway/gene-set to be perturbed).
