WebGene-set analysis, however, revealed that methylation variation in all six circadian-related genes was significantly associated with all studied metabolic traits (all P’s≤0.0009). Conclusion: DNA methylation variation in circadian-related genes jointly contributes to metabolic function, independent of genes and early family environment. WebAdditionally, errors in DNA recombination can occur when genes are recombined to create a new combination of genetic information, which can lead to a change in the expression of the gene. Finally, DNA repair systems can malfunction and cause errors in the repair process which can result in permanent changes to the DNA sequence.
