Fig. 1From: Screening of nucleotide variations in genomic sequences encoding charged protein regions in the human genomeAverage fraction of variants within charge clusters and their corresponding background sequences. The variant fractions were calculated according to the formula in the Methods section (The recovery of the variant data) within negative (a) and positive (b) charge clusters and their corresponding genes, full mRNAs and intron + exon sequences. Variant fractions within clusters of both charges (a and b) are in average bigger than those within their genes, full mRNAs and exon + intron sequencesBack to article page
