Replicating an association with asthma [24] (chr15:30,912,719–32,516,949; ORmirror = 0.17; 95%-CI [0.08; 0.35]; p = 1.2 × 10−6) which parallels the previously reported decreased forced vital capacity [27] and peak expiratory flow [23], this was the only association at the locus driven by deletions, with prevalence being increased in only BP4-5 (46.2%; pt-test = 1.8 × 10−5) but not D-CHRNA7-BP5 deletion carriers (16.7%; pt-test = 0.538), compared to copy-neutral individuals (12.1%) (Fig. 6E). Here, CHRNA7 is linked to asthma.
