Functional bias of genes having nonsense SNPs not causing NMD.

aNumber of genes with a molecular function in the 602 genes in which nonsense SNPs causing NMD were found.bExpected number of genes that have a biological function in a sample of 602 genes, assuming a proportion of genes with a molecular function in all human genes.cEnrichment of a biological term in the genes for nonsense SNPs was statistically evaluated as a upper probability in a hypergeometric distribution.
