Haplotype analysis of the HNF1A-AS1 rs7953249 and the HNF1A rs735396 polymorphisms demonstrated a significant association of the rarest AC haplotype with the lower levels of GP24, GP28 and GP30 N-glycans and nominally significant association with the lower levels of GP37 N-glycan in the PTSD subjects (Table 4, Figure 3, Supplementary Table S3). This evidence concerns the gene HNF1A and post-traumatic stress disorder.
