Noteworthy genes adjacent to top EWAS CpGs include CFDP1 (Cranio Facial Development Protein 1) and PRKAR1B (Protein Kinase CAMP‐Dependent Type I Regulatory Subunit Beta) which are related to fibroblastic disorders, while MAN2A1 (Mannosidase Alpha Class 2A Member 1), PSAT1 (Phosphoserine Aminotransferase 1), GNAS (GNAS Complex Locus), and SPTBN1 (Spectrin Beta, Non‐Erythrocytic 1) are linked with cystic fibrosis (Chen et al., 2013). The gene discussed is PRKAR1B; the disease is cystic fibrosis.
