Wang et al. (18) identified heterozygous variants c.2T>C, p.(Met1Thr) and c.1774_1775del, p.(Leu592Aspfs*5) in the RSPH4A gene, which were associated with bronchiectasis and infertility, and c.2T>C, p.(Met1Thr) may be a hotspot variant in Chinese. This evidence concerns the gene RSPH4A and bronchiectasis.
