This is in line with results from another cohort of individuals concomitantly presenting interstitial pneumoniae, autoimmune diseases, and RTEL1 variants in heterozygosity [41]: similarly to COVID-19 population, such patients also showed clinical manifestation related to a telomere syndrome, such as hematological abnormalities (i.e., neutrophil and lymphocyte alterations) and liver pathologies, along with an earlier manifestation of the pulmonary disease [42, 43]. Here, RTEL1 is linked to telomere syndrome.
