Input: Consider Input: Question: Are polymorphisms in SPINK5 associated with asthma in a Dutch population?
Answer: The negative results in this study suggest that SPINK5 is not associated with asthma or atopic phenotypes in individuals ascertained by a proband with asthma. This is consistent with the finding that SPINK5 is not expressed in the lung. Because our patients were ascertained for asthma, a role of SPINK5 in atopic dermatitis cannot be excluded.

Output: no
