Mutations in the WRN gene lead to the Werner syndrome (WS), which resembles premature aging. Here, we hypothesize that genetic variations in the WRN gene may also influence aging-trajectories in the population at large. To test this hypothesis, we assessed the impact of the i1-C/T, L1074F and C1367R polymorphisms in the WRN gene on the occurrence of cardiovascular pathologies, on cognitive performance and on the risks of all-cause, cardiovascular and cancer mortalities in the population-based Leiden 85-plus Study. This prospective follow-up study includes 1,245 participants aged 85 years and older, with a total follow-up of 5,164 person-years. At baseline the risks of myocardial infarction, myocardial ischemia, intermittent claudication, arterial surgery and stroke dependent on the i1-C/T, L1074F and C1367R polymorphisms, did not vary between the different genotypes. Also no differences in cognitive functioning were observed, except for attention, where carriers of the 1367R allele performed worse compared to the 1367C homozygotes (94.2 (4.35) versus 84.8 (1.84), p=0.04). Mortality risks, calculated separately for all SNPs, were similar between the different genotype carriers of the i1-C/T, L1074F and C1367R polymorphisms, showing no evidence of altered survival. In conclusion, the i1-C/T, L1074F and C1367R polymorphisms in the WRN gene do not influence the aging-trajectories and survival in the population at large.

Werner syndrome is a rare autosomal recessive disorder, caused by mutations in the WRN gene. Clinical findings include: senile appearance, short stature, grey hair, alopecia, bird-like face, scleroderma-like skin changes, skin ulcers, voice abnormalities, cataracts, osteoporosis, type 2 diabetes mellitus, ischemic heart disease and hypogonadism. The syndrome begins to become apparent in adolescence but it is usually diagnosed in the third or fourth decade of life. Since the patients usually die by the age of 40-50 years related to malignant neoplasms or atherosclerotic complications, they should be closely followed and treated for complications.
