Genes separate fibrotic from non-fibrotic HP

This paper suggests that a patients genes, particularly MUC5B and those related to short telomers, are the underlying reason why some patients with hypersensitivity pneumonitis develop the fibrotic variant. It implies, although is not stated, that the genes are more important than cessation of exposure to the progression to fibrosis.
