From: A review of epigenetic changes in asthma: methylation and acetylation
Oral contraceptive pills (OCP), which are used in different conditions, at the age of menarche, can affect GATA3 methylation level in cytosine-phosphate-guanine (CpG) sites via, presumably, sex hormones. Interaction between GATA3 single-nucleotide polymorphisms (SNPs) and OCP is influenced by these methylation changes, which affect the immunological process leading to asthma
