AbstractIdiopathic Pulmonary Fibrosis (IPF) is the most common type of Idiopathic Interstitial Pneumonias (IIP). The aim of this study is to determine the mutation of variants in four telomere-related genes and to determine the possible relationship between these mutations and telomere shortening in order to contribute to the understanding of the pathophysiology of IPF. For this study, 34 individuals with IPF, 32 individuals with non-IPF ILD (Interstitial Lung Disease), and 31 healthy controls between the ages of 40 and 85 were included. The mutation analysis and telomere measurements were examined for the volunteers. According to the mutation screening results, no significant difference was found between the patients with IPF, non-IPF ILD groups and healthy individuals in terms of genotyping analysis. However, in terms of the allele distribution for two genes, statistically significant difference was found in IPF and non-IPF ILD patients (TERT; p = 0.002 and TERC; p = 0.001). According to the telomere length measurement, the telomeres of the patients were shorter than of the control group (p = 0.0001). In compliance with the results of our analysis, it is thought that genes that have allelic significance from the point of gene mutations as well as telomere shortening may be risk factors for the disease.
