FHL2 and alcohol abuse: The mean difference in obtained DNA methylation levels comprised 2.1, 2.8, and 3.0 for C1, C2, and C3 in MIR29B2CHG, respectively, and 1.7 for C7 in FHL2. As DNA methylation decreases with age in the case of MIR29B2CHG, this suggests a slightly faster aging of alcohol abusers.
