Likewise, higher levels of GP20, GP33 and GP35 N-glycans and nominally higher levels of GP27 N-glycan in the control subjects, as well as higher levels of GP27, GP33, GP35 and GP39 N-glycans in PTSD patients were associated with T allele of the HNF1A rs735396 polymorphism (Table 4, Figure 3, Supplementary Table S3). The gene discussed is HNF1A; the disease is post-traumatic stress disorder.
