The MUC5B variant is also not considered a risk factor in ASSD [89], myositis [90], or sarcoidosis [76]; however, the MUC5B rs35705950 promoter variant appears to be associated with asbestosis [11], potentially due to the fact that asbestosis shares radiological and pathological UIP features with IPF. This evidence concerns the gene MUC5B and sarcoidosis.
