TASK: Your task is to answer biomedical questions using the given abstract. Only output yes, no, or maybe as answer.
INPUT: ['Chronic obstructive pulmonary disease (COPD) is a complex disease in which multiple genes and their interaction with environmental factors contribute to disease development. Recent genome-wide association studies in COPD revealed the chromosome 4 region near hedgehog interacting protein (HHIP). However, these studies were mostly performed in Caucasians, and additional studies in multiple ethnic groups are needed. We investigated genetic associations of HHIP in Korean COPD and control subjects.', 'Two separate case-control studies were performed. Firstly, 139 subjects with COPD and 199 control subjects were selected from the Soonchunhyang University Bucheon Hospital Biobank. Secondly, 219 individuals with COPD were recruited from the Korean Obstructive Lung Disease (KOLD) cohort. The control subjects consisted of 305 smokers or ex-smokers with normal lung function who were registered in the Korean Genome Epidemiology Study. Associations between COPD susceptibility and single-nucleotide polymorphism (SNP) genotypes were tested by logistic regression. Associations between lung function and SNP genotypes were tested by linear regression.', 'In the first study, the mean forced expiratory volume in 1 s (FEV1 ) of these COPD subjects was 1.32 L. None of 15 SNP was significantly associated with COPD susceptibility. However, four SNP associated significantly with FEV1 in subjects with COPD. In the KOLD cohort study, two SNPs (rs11938704 and rs10013495) near HHIP were significantly associated with FEV1 (P = 0.0001 and 0.001, respectively) in subjects with COPD.'] Are genetic variants in HHIP associated with FEV1 in subjects with chronic obstructive pulmonary disease?
