Figure 2.
The figure shows the nature of the interaction between KL SNP rs9527025 and PTSD symptom severity on raw (beta) methylation levels at the KL locus cg00129557 for n = 308 participants in this cross-sectional analyses. The protective effects of the minor allele (C) were attenuated at high levels of PTSD symptom severity. This SNP is located on chromosome 13 at 33,628,193 bp; cg00129557 is located on chromosome 13 at 33,607,618 bp. There were 9 participants homozygous for the minor allele (CC), 88 heterozygous (CG), and 211 (GG) homozygous for the major allele.
