KIF15 and idiopathic pulmonary fibrosis: In a cohort of approximately 138 patients, carriers of KIF15 missense variants were diagnosed at a significantly younger median age of 54 years compared with 72 years in non-carriers (p = 0.023) and showed higher rates of early lung transplantation or mortality, highlighting KIF15 as a potential prognostic biomarker for early-onset and severe IPF [30].
