Table 2. Genomic distribution of UTRs associations.

The table reports, from left to right: the UTR type, the number of variants included in the GWAS Catalog and localised in the UTRs, the average length of the 5′UTR and 3′UTR expressed in bp and, in parentheses, the number of genes used in the calculation, the genomic length calculated as the product of the average length for the number of genes considered, and the number of associated variants per each kb of UTRs’ length. The average length has been calculated using all genes associated with an Ensembl Identifier and having an UTR.

Region type	N GWAS variants in the region	Average length (N genes)	Genomic length	N variants per kb
5′UTR	442	151.5 bp (18,714)	2,835 kb	0.16
3′UTR	1,652	872.2 bp (18,770)	16,371 kb	0.10
