Logistic and linear regression was used to examine the associations between the FKBP5 SNP rs1360780 and the CRHR1 SNP rs17689918 with PTSD diagnosis and severity, as well as general psychiatric symptom severity, separately for current and remitted PTSD patients.
However, subjects who had experienced a moderate or severe history of childhood abuse and who were also GG homozygotes for rs110402 showed significant improvement after treatment with GSK561679 (n = 6) but not with placebo (n = 7) on the PTSD Symptom Scale-Self-Report.
To determine if single nucleotide polymorphisms of the corticotrophin-releasing hormone binding protein (CRHBP, rs10055255) and CRH receptor type 1 (CRHR1, rs1876831) were associated with posttraumatic stress disorder (PTSD) and depressive symptoms following medical-surgical intensive care unit (ICU) hospitalization.
Results indicated that multiple SNPs were associated with acute symptoms at a univariate level, and after correction for multiple testing, rs12944712 was significantly related to acute PTSD symptoms.
