Genome-wide association study on susceptibility genes associated with yang-deficiency constitution: A small sample case-control study.

Objective: To explore susceptibility genes associated with yang-deficiency constitution using single nucleotide polymorphism (SNP) genotyping.

Methods: Based on an epidemiological survey, 30 volunteers with yang-deficiency constitution and 30 volunteers with a balanced constitution were included according to the Classification and Determination Standards of Constitutions in Traditional Chinese Medicine. Peripheral blood was collected and DNA was extracted from white blood cells.
