Specifically, research partnerships often suffer from imbalances, such as \"helicopter\" research approaches or the exploitation and marginalization of LMIC researchers. Here, we present a consensus report by members of the International Society for Psychiatric Genetics, outlining key considerations and strategies for planning, implementing, and disseminating equitable collaborative research. Throughout the collaboration process, we identified both challenges and opportunities and provided recommendations to maximize the benefits of these partnerships. Among our considerations, we emphasize that Equitable Collaboration must begin with comprehensive stakeholder engagement, fostering a participatory environment that includes local communities, governments, and institutions from both HICs and LMICs. Among the potential challenges we identify are differences in ethical research and data-sharing frameworks across countries, inequalities in research resources and infrastructure, and reduced visibility of research conducted in LMICs. These factors can significantly impact research outcomes and their applicability. In conclusion, while global collaboration in psychiatric genetics presents complex challenges, it also offers substantial opportunities for impactful research and improved global mental health.</p>","PeriodicalId":520553,"journal":{"name":"American journal of medical genetics.

For each gene set, we generated gene set polygenic risk scores (gsPRSs), which sum the effects of SNPs for each selected gene set. We created gsPRS for ADHD and for phenotypes that are genetically correlated with ADHD. These gsPRS were added to the standard PRS as input to machine learning models predicting ADHD. On the test subset, a random forest (RF) model using PRSs from ADHD and genetically correlated phenotypes and an optimized group of 20 gsPRS had an area under the receiving operating characteristic curve (AUC) of 0.72 (95% CI: 0.70-0.74). This AUC was a statistically significant improvement over logistic regression models and RF models using only PRS from ADHD and genetically correlated phenotypes. Summing risk at the gene set level and incorporating genetic risk from disorders with high genetic correlations with ADHD improved the accuracy of predicting ADHD.

Finally, functional enrichment analysis identified biological processes, molecular functions, and cellular components associated with the genes linked to FC. Our findings revealed that FC between the medial cerebellum and several cortical regions, including the occipital, temporal, parietal, and mid-insular cortices, was positively associated with somatic symptom severity. Similarly, FC between the parietal cortex and regions such as the anterior prefrontal cortex, ventral frontal cortex, temporal cortex, and precuneus also showed positive associations with somatic symptom severity. Moreover, connectome-transcriptome correlation analysis revealed that the expression of 1120 genes was spatially correlated with FC, and these genes were primarily enriched in synapses and ion channels.

Here, we review the current literature on the genetics of response to these treatment modalities. To date, the limited number of studies done to investigate genetic predictors of treatment response have primarily focused on single variants in candidate genes, and none of these have been consistently reproducible. The majority of candidate gene studies examine the effect of variants in the COMT and BDNF genes on treatment response. There are a limited number of genome-wide association studies (GWAS) looking at treatment response, though they are almost all underpowered, with only one study including a sample size > 1000. As a result, there have been few single nucleotide polymorphisms (SNPs) found to be associated with treatment response at a statistically significant level, all in genes other than COMT and BDNF. The challenge is now to generate data from a large group of patients undergoing these therapies in order to more robustly assess the genetic factors affecting treatment response. This will not only help establish genetic predictors of response, but also potentially develop differential predictors of response to available treatments, which could provide clinicians with critical information to aid in deciding which treatment modality to recommend for treatment-resistant depression.

The largest GWAS identified eight major loci with stronger genome-wide significance for epilepsy, regardless the underlying epileptic syndrome: 2q24.3, 2p16.1, 4p15.1, 7q21.11, 8p23.1, 9q21.13, 10q24.32, 16q12.1, 2p16.1 and 2q24.3 occurred more frequently in patients with genetic generalized epilepsies.
