A potential role for beta\u20102 adrenoceptor (\u03b2<jats:sub>2<\/jats:sub>AR) polymorphisms in these relationships was also sought as a secondary objective. Of the original 73 children, wheezing history was available in 65 (89%), and 49 (67%) attended the laboratory for physiological measurements and genotyping of \u03b2<jats:sub>2<\/jats:sub>AR. Wheezing was categorized as occurring 1) only before the fourth birthday, 2) after the fourth birthday, or 3) never. No relation was seen between neonatal and later lung function. However, neonatal bronchial responsiveness predicted subsequent FEV<jats:sub>1<\/jats:sub> (<jats:italic>P<\/jats:italic>\u2009=\u20090.03). Increased neonatal bronchial responsiveness was associated with transient wheeze &lt;4 years but not with later wheeze. Neonatal V\u2032maxFRC was reduced in those possessing Gln<jats:sup>27<\/jats:sup> or Arg<jats:ext-link xmlns:xlink=\"http:\/\/www.w3.org\/1999\/xlink\" xlink:href=\"#bib16\">16<\/jats:ext-link> alleles, but there was no effect of \u03b2<jats:sub>2<\/jats:sub>AR polymorphisms on FEV<jats:sub>1<\/jats:sub> at 10 years. Wheeze after 4 years of age was typical of classical asthma, as it was strongly related to atopy and bronchial responsiveness at age 10. In conclusion, we confirmed the association of neonatal bronchial responsiveness with both early wheezing and later lung function. We also showed an influence of polymorphisms at both aa16 and aa27 on neonatal lung function. Wheezing beyond 4 years, typical of classical asthma, was unrelated to early measurements of lung function or bronchial responsiveness.
