The TERC C/T allele association with TL showed an increased risk of colorectal cancer (longer TL) (Jones et al., 2011), idiopathic pulmonary fibrosis (shorter TL) (Sousa et al., 2019) and multiple sclerosis (longer TL) (Hecker et al., 2021). The gene discussed is TERC; the disease is pulmonary fibrosis.
