From: Estrogen-dependent association of HDAC4 with fear in female mice and women with PTSD

Genetic variation in HDAC4 associates with fear expression. (a) Schematic of the human physiology experiment. (b) Average fear-potentiated startle (FPS) difference score across the fear extinction phase for CC and CT/TT genotypes. (c) Average FPS difference score across the conditioning and expression (extinction) session for genotype X post-traumatic stress disorder (PTSD).
