I am in the #WCPG2022 IDEA plenary, which discusses the need and approaches to decolonising psychiatric genetics. Panel members are Olivia Matshabane, Paola Giusti-Rodriguez @paolagiustirodriguez, @hailianghuang, and @MeeraPurushott1. Chairs are Lea Davis and John Nurnberger.
[I will tweet as much as I can here, but a discussion is always more challenging to tweet]
First question highlights the impact of colonialism in research. This includes lack of resources and support for ECRs, the need for engaging with and working alongside studied groups throughout the research process, including subsequent data storage, access and usage. #WCPG2022
Leadership is also raised - particularly the issue of external scientists failing to appreciate the sociocultural context of where the research is done, and generating conclusions that are incorrect or stigmatising #WCPG2022
Return to the idea of support for ECRs - part of the impact of colonialism has been the imposition of more hurdles for local ECRs, needing to continually prove themselves on a sociocultural level even before having to prove themselves on a scientific one #WCPG2022
Local understanding is important across research, from the terms and labels used in the research through to the processes of delivering and sharing research. Need for respect and communication, but also for promoting and ensuring local leadership #WCPG2022
What does decolonisation mean in this context? Power imbalance across history that needs to be addressed - in part this can be through equal engagement across groups. Also need to appreciate local context and needs, from the intellectual to the practical #WCPG2022
Academic credit varies considerably across countries - credit is challenging regardless, but need fair ways of allocating credit (and again understanding local contexts) #WCPG2022
Decolonisation is a long term student movement, beginning in South Africa and now globally. #WCPG2022
Lack of representation of people in LMICs in genetic reference risks medical inequalities #wcpg2022
Framework for decolonisation - self, research, access, partnership, inclusion. Needs to be multidisciplinary and bidirectional, involving stakeholders across life experiences as well as across academic disciplines #WCPG2022
Need cultural competence and cultural humility. That extends to the terms and concepts we use - for example, no specific terms for schizophrenia etc. in Xhosa (just mental illness as a general term) #WCPG2022
Currebt systems for credit and dissemination is text-based, which isn't culturally universal - other cultures tend to disseminate orally. Language is also important - English far over used in scientific discourse over others. Need local language papers #WCPG2022
Also just racism - judging competence according to ethnicity of names, the request for "native speakers" to review papers etc. #WCPG2022
What partnerships work well? @H3Africa - focus on African-led scientific and infrastructural development, with African contexts and sensitivities. Need to learn from such projects and establish similarly successful efforts in psych genomics globally #WCPG2022
@LAGCPsychGene: learning what works. Lots of interest in collaboration, increasing understanding of needs. Funding is a challenge, much more investment available from US. Establishing presence in countries and growing from there in a targeted way is effective #WCPG2022

PGC 1000+ scientists from 50+ countries. Primary funding from NIH, but many others as well. 8 sites, 16 PIs in USA, UK, and Ireland. Coordinating committee including regional representatives. #WCPG2022
Next is Omar Shanta who will talk about a GWAS of CNVs in 500k individuals (127k cases, mostly EUR, some AFR). Needed consistent CNV calling across entire cohort. Difficult platforms, which makes things challenging. #WCPG2022
Aims: what is the contribution of rare CNVs, which are those CNVs per disorder, how do rare CNVs compare across disorders? #WCPG2022
Assess multiple metrics of CNV burden, comparing tier 1 (pli > 0.5) and tier 2 (pLI < 0.5). #WCPG2022
I'm back (after a slightly longer lunch) - @juandelahozco is presenting on longitudinal trajectories in the EHR from the Clínica San Juan de Dios, Manizales, Colombia. #WCPG2022
Diagnoses of severe mental illness from ICD10, validated against structured interview and chart review. Some BIP-MDD mismatches (see tweets on @loldeloo talk earlier), but agreement is generally very good, especially for SCZ #WCPG2022
Want to extract presentation information from notes - developed NLP algorithm, required named entity recognition and negation detection. Extracted features align with ICD10 codes #WCPG2022
I am in the PUMAS session at #WCPG2022, listening to @b_gelaye talking about the NeuroGAP study
NeuroGAP seeks to build collaboration across Africa, particularly across early career researchers. Phenotyping working group has members across Kenya, Uganda, Ethiopia and South Africa, as well as from the Broad. Lots of clinicians, valuable for building phenotypes #WCPG2022
8 phenotyping manuscripts accepted, 8 more to come, describing the details of psychiatric phenotyping within and across different African countries #WCPG2022
It's day 3, and @sebatlab is outlining the spectrum of genetic influences that affect autism. Clear that although there are strong rare variant effects, these are not monogenic disorders #WCPG2022
Combining together results from common, rare, and structural variants allows a broader picture of genetic risk. See over-transmission of genetic risk at all levels from parents to affected children #WCPG2022
Can combine common and rare variants together into scores that are more predictive than either score alone. Inverse correlation - individuals with autism with high rare score tend to have lower common score [conditional on having autism - crosses liability threshold] #WCPG2022
