Inclusion criteria

Inclusion criteria: 1. To meet the 1999 consensus of Multiple Chemical Sensitivity. 2. 20 years of age and older 3. first-person informed consent

Exclusion criteria

Exclusion criteria: 1. Comorbid with mastocytoma or porphyria 2. Only due to psychogenic disorder 3. Comorbid with severe asthma to prevent the diagnosis of multiple chemical sensitivity 4.

Design outcomes

Primary

MeasureTime frame
Comparison of single nucleotide polymorphism between control and the patients with multiple chemical sensitivity.P value is less than 5X10^-8.

Secondary

MeasureTime frame
P value from 5X10^-8 to 1X10^-5 is highly suggestive association, P value from 1X10^-5 to 1X10^-4 is moderately suggestive association.
