Description
Nahyun Kim, Jooyeon Park, In Deok Kong, Tonda L. Hughes, and Dae-Kwang Kim compare mitochondrial DNA patterns and white cell telomere length in teenage boys with and without internet gaming addiction, in 2026 work. Questionnaires sorted 206 male adolescents into addiction and comparison groups. Blood tests measured repeat patterns in two control regions of the mitochondrial genome, mitochondrial copy number, and telomere length, the cap that shortens as cells age.
One repeat pattern at the first region was rarer in the addiction group and at first looked protective in adjusted models, yet the link faded after strict correction for many tests. Mitochondrial copy number did not differ between groups. Telomeres ran clearly shorter in the addiction group, above all in boys carrying either of two repeat patterns, and addiction stayed tied to shorter telomeres after adjustment. The authors call the gene link preliminary and the telomere link the firmer signal.
