There is an emerging number of studies that have reported sex differences in the findings from GWAS of psychiatric disorders. Table 2 presents a summary of findings of recent GWAS that have presented sex stratified analyses, the number of genome‐wide sex‐specific significant SNP associations, and sex‐specific SNP based heritability (h 2 SNP). There are significant sex differences for ADHD, 95 alcohol dependence, 113 ASD, 114 anorexia, 115 Major Depressive Disorder (MDD), 116 Obsessive‐Compulsive Disorder (OCD), 117 PTSD, 118 and substance use disorder. 119 Sex stratified GWAS have not been published for anxiety disorders, bipolar disorder or schizophrenia. However, there may be studies that have completed sex‐stratified analyses but did not report the findings if they were negative. 120
