A recent genome-wide association study has shown an association between a polymorphism in FAM13Ars2609255 and idiopathic interstitial pneumonias in a Caucasian population.
Variants in FAM13A have been found in genome-wide association studies (GWAS) to associate with lung function in the general population as well as in several common chronic lung diseases (CLD) such as chronic obstructive pulmonary disease (COPD), asthma, as well as in idiopathic interstitial pneumonias (IIP).
