Meta-analyses revealed individuals with MS and depression had a higher depression PGS compared to both MS without depression (odds ratio range per standard deviation [SD]: 1.29-1.38, P<0.05) and healthy controls (odds ratio range per SD: 1.49-1.53, P<0.025), regardless of the definition applied and when sex-stratified. The BMI PGS was associated with depressive symptoms (P≤.001). The depression PGS did not differ between depression occurring as a comorbid condition with MS or as the primary condition (odds ratio range per SD: 1.03-1.13, all P>0.05).Discussion: Higher depression genetic burden was associated with ∼30-40% increased odds of depression in European genetic ancestry participants with MS compared to those without depression and was no different compared to those with depression and no comorbid immune disease. This study paves the way for further investigations into the possible use of PGS for assessing psychiatric disorder risk in MS and its application to non-European genetic ancestries.
