Some molecular-genetic determinants of premature aging in women

Background. Accelerated biological aging is associated with age-related diseases and an increased risk of mortality. Genetic predisposition may be an important factor in this process. Aim. To determine the significance of genetic polymorphisms in the VDR and COL1A1 genes in accelerated aging. Materials and methods. The study included 100 women aged 20–35 years, divided into groups with accelerated (Group 1) and normal/slow (Group 2) aging rates. We assessed biological age using V.P. Voytenko's formula. Genetic polymorphisms analyzed were: VDR 283 AG (Bsml), VDR 2 AG (Fokl), COL1A1 1546 GT, COL1A1 -1997 CA. Results. The VDR 283 AG (AA) polymorphism was associated with accelerated aging, occurring more frequently in Group 1 (18% vs 4% in Group 2, p=0.025). The COL1A1 -1997 CA polymorphism was more prevalent in Group 2 (76% vs 56% in Group 1, p=0.035). A multifactorial model identified combinations of polymorphisms that predict accelerated or slow aging with an accuracy of 0.72. Conclusion. Genetic predisposition plays a significant role in accelerated aging. Analysis of VDR and COL1A1 polymorphisms can help identify the risk of premature aging and may serve as a basis for further research and the development of new approaches to prevent age-related diseases.
