1. Introduce the reference of a SNP of interest, as an example:
rs429358, in a database (dbSNP or other).
2. Find MAF/MinorAlleleCount link.
MAF/MinorAlleleCount: C=0.1506/754 (1000 Genomes, where number of genomes sampled = N = 2504); where
C is the minor allele for that particular
locus;
0.1506 is the frequency of the C allele (MAF), i.e. 15% within the 1000 Genomes database; and
754 is the number of times this SNP has been observed in the population of the study. To find the number, note that 0.1506 = \frac{754}{2 \times 2504}, where 2\times is to account for
diploidy. ==See also==
