Phosphosite data was downloaded from Phosphosite.org (Sep 25, 2014) http://www.phosphosite.org/staticDownloads.do Variation data from 1000 genome FTP server (phase 3, v5.20130502). Protein positions were mapped to chromosomal positions using CCDS version 15 Uniprot Uniprot Identifier of phosphorylated protein Position Position in Uniprot sequence of phosphorylation site Chromosome Chromosomal.position Alteration Reference allele / alternate allele ENST ENSEMBL transcript ID Effect Reference amino acid / alternate amino acid HGNC HUGO identifier Pos Position in ENSEMBL transcript AA Ancestral allele AC Total number of alternate alleles in called genotypes AF Estimated allele frequency in the range (0,1) AFR_AF Allele frequency in the AFR populations calculated from AC and AN, in the range (0,1) AMR_AF Allele frequency in the AMR populations calculated from AC and AN, in the range (0,1) AN Total number of alleles in called genotypes DP Total read depth EAS_AF Allele frequency in the EAS populations calculated from AC and AN, in the range (0,1) EUR_AF Allele frequency in the EUR populations calculated from AC and AN, in the range (0,1) NS Number of samples with data SAS_AF Allele frequency in the SAS populations calculated from AC and AN, in the range (0,1) LT Number of low throughput experiments this site has been seen in HT Number of high throughput experiments this site has been seen in
