STIP1 and asthma: 3 STIP1 single-nucleotide polymorphisms (SNPs; rs4980524, rs6591838 and rs2236647) were found to be associated with ICS response in a white adult population [13] and another study found STIP1 rs2236647 polymorphism was also associated with the risk of asthma in adult population of Arab descent [14].
