Not so long ago, there was a hope in the research community that common genetic variation, i.e. variants present
at minor allele frequencies > 5 % in human populations, might explain most or all of the heritability of common complex disease.

To understand how the different
alleles influence the immune response to vaccination, the researchers next looked in more detail
at immune cells from 47 of the patients (34 had two major T
alleles, and 13 had
at least one
minor G
allele).
We tested the hypothesis that the frequency of the
minor Ser482
allele at the PPARGC1A locus is lower in World - class Spanish male endurance athletes (cases)[n = 104; mean (SD) age: 26.8 (3.8) yr] than in unfit United Kingdom (UK) Caucasian male controls [n = 100; mean (SD) age: 49.3 (8.1) yr].
They're not all rare variants, either: 86 million variants are classified as common (G5, G5A, or COMMON), with
minor allele frequencies > 1 % in
at least one population.
