Fig. 2: rs11740584 and rs2299007 minor allele creates methylated CpG sites and alter KIF3A expression.

Skin tape (a, b), and nasal epithelial cell (c, d), methylation levels at rs11740584 and rs2299007 CpG sites in homozygous and heterozygous alternate allele carriers. A one-way ANOVA was conducted to compare effects of genotype on methylation levels. Each panel includes n = 54 biologically independent samples examined over two independent experiments. Data are presented as mean values ± SD. e Experimental design of allele-specific gene expression illustrating the location of the SNPs, their linkage, and the KIF3A gene. f Fold-change in expression in nasal epithelial and primary keratinocyte cells are provided relative to the C allele. Data are presented as mean values ± SD of three individuals in technical quadruplicates examined over two independent experiments per tissue type. Linear mixed models were performed to access the expression difference between risk allele and reference allele. P values of two-sided testing were reported for all the tests. NEC = nasal epithelial cells. Source data are provided as a Source Data file.
