For the current studies the deCODE (Kong, et al., 2002) genetic map was used. The position of each SNP was determined by interpolation using markers that were both on the genetic map and for which an unambiguous physical map position was available in NCBI build 35. Any markers that were not in the same relative order in both the genetic and physical maps were omitted as anchors for the interpolation of the genetic positions of the SNPs.
