The genetic risk factors for PTSD include several genes, such as the solute carrier family 6 member 4 gene (SLC64A), FK506 binding protein 5 gene (FKBP5), gamma-aminobutyric acid (GABA) A receptor alpha 2 gene (GABRA2), a regulator of G-protein signaling 2 gene (RGS2), and Cordon-bleu WH2 repeat protein gene (COBL) [2]. The gene discussed is COBL; the disease is post-traumatic stress disorder.
