These data have been extracted from the 1000 Genomes data.
The data set contains the genotype matrix TTN.gen, the pedigree matrix TTN.fam and a matrix TTN.bim,
corresponding to 503 individuals of European populations and 733 SNPs on chromosome 2, on a ~600kb segment
containing the Titin gene. There is also a factor TTN.pop, which gives the population from which each
individual is drawn (CEU = Utah residents of Northern Western European ancestry, FIN = Finnish, GBR = England and Scottland,
IBS = Iberian, TSI = Toscani).
