Comparisons between the CRHR1 (rs878886) and 5HTTLPR genotypes with regard to trait anxiety, neuroticism, shock intensities, baseline startle amplitude and raw startle data across conditions (light on/CXT+, light off/CXT+, light off/CXT–) and phases did not reveal significant differences (all p-values >.10). The gene discussed is CRHR1; the disease is Anxiety.
