Kj. Holroyd et al., ASTHMA AND BRONCHIAL HYPERRESPONSIVENESS LINKED TO THE XY LONG ARM PSEUDOAUTOSOMAL REGION, Genomics (San Diego, Calif.), 52(2), 1998, pp. 233-235
We examined the long arm XY pseudoautosomal region for linkage to asth
ma, serum IgE, and bronchial hyperresponsiveness. In 57 Caucasian fami
lies multipoint nonparametric analyses provide evidence for linkage be
tween DXYS154 and bronchial hyperresponsiveness (P = 0.000057) or asth
ma (P = 0.00065). This genomic region is approximately 320 kb in size
and contains the interleukin-9 receptor gene. These results suggest th
at a gene controlling asthma and bronchial hyperresponsiveness maybe l
ocated in this region and that the interleukin-9 receptor is a potenti
al candidate. (C) 1998 Academic Press.
