Genome-wide rare variant studies of IPF patients of non-European ancestry have been understudied. Here, we evaluate the enrichment of rare genetic variants of 241 unrelated non-European cases, representing individuals of Latino, African, South Asian, East Asian, and Other Admixed ancestry. Gene burden analysis of deleterious rare (protein-truncating and missense) variants demonstrate an excess of TERT rare damaging variants (OR 67.1, 95% CI [23.1, 195.0], P = 9.4 x 10-14) in non-European subjects. Analysis by ancestry demonstrated an excess of rare, damaging TERT variants in the Latino subgroup (OR 80.9, 95% CI [17.3, 383.8], P = 2.6 x 10-8). Although the non-European group did not show enrichment of PARN, RTEL1, and KIF15 rare deleterious variants, these groups all showed a trend in the same direction as the European ancestry group. For TERT and KIF15, the inclusion of IPF patients of non-European ancestry led to a higher odds ratios and increased evidence in favor of rare deleterious variant contributions, thus demonstrating the increased power of multi-ethnic studies over single-ethnicity studies. To our knowledge, this is the first study that confirms the involvement of rare deleterious TERT variants for IPF patients of Latino and non-European ancestry. To better understand the genetic underpinnings of IPF patients of all ancestries, additional work will be needed to broaden patient recruitment to normalize imbalances.
