Abstract [en]

Despite rapid advances in whole-genome sequencing (WGS), translating genomic findings into individualized insights remains challenging. We present GenRiskPro, a clinical decision-support and research platform, which automates WGS variant calling, annotation, prioritization, and reporting to deliver actionable findings and facilitate precision wellness. (To test the GenRiskPro platform, log on to https://www.phenomeportal.org/dashboard using the following credentials: Username: user@test.com; Password: test.) GenRiskPro integrates rare and common variant prioritization in a unified pipeline and in-house database, enabling both rare and complex disease and trait association analyses. Variant reporting is supported via LongevityCloud, which features a web portal for clinicians to review, adjust, and authorize the return of results in tabular and PDF formats, alongside a mobile app with artificial intelligence (AI) integration for sequenced individuals. Case studies using Turkish (TR, n = 275) and Swedish (SW, n = 101) WGS data assessed platform performance and variant prioritization: (a) predefined gene panels yielded a 1.82% positive rate for actionable findings per American College of Medical Genetics and Genomics (ACMG) secondary findings guidelines; (b) phenotype-driven support diagnosed cases including muscular dystrophy and microcephaly; (c) cohort-level ClinVar reassessment identified potentially misclassified pathogenic variants; (d) rare variant burden analysis revealed enrichment in ABCA4 for TR and SMPD1 in SW; and (e) population analysis highlighted carrier differences in trait-associated SNPs (rs12913832 and rs4988235) and PGx variants (CYP2B64 and CYP2B66). GenRiskPro unifies databases, literature, web development, and AI for rapid, user-friendly genomic analysis and reporting, which fosters collaboration among hospitals, researchers, clinicians, and patients.

Abstract [en]

Genomics represents the first layer of the central dogma, where variations in the genome influence downstream biological processes and finally affect human phenomics. Although next-generation sequencing (NGS) technologies have generated massive amounts of genomic data, gaps remain in translating genomics into clinical and precision medicine applications.

The first part of this thesis (Papers I–II) focuses on developing high-performance computational platforms for clinical genomic and research applications. In Paper I, we developed GenRiskPro, a platform designed to enhance connectivity among key stakeholders in clinical genetics, including hospitals, research facilities, clinicians, and patients. It prioritizes reporting genetic risk variants for rare diseases and includes tools for detecting pharmacogenomic (PGx) and lifestyle-associated variants affecting complex traits. We also revealed population-specific genetic heterogeneity in the enrichment of pathogenic and low-to-rare-frequency risk variants, which frequently exhibit low penetrance in their phenomic presentations.

In Paper II, we developed OncoRisk, a comprehensive web server integrating multiple precision oncology knowledge bases and pan-cancer cohorts. The server comprises four major modules. It enables the query of key oncogenic terms such as mutations, gene fusions, diseases, and therapies, and supports analysis of individual tumor sequencing data to identify potentially significant mutations by mapping with known oncogenic resources. We also built functions for fast visualization and analysis of cancer cohort data and for querying of mutation frequencies for specific genes or variants across large-scale cancer sequencing cohorts.

The second part of this thesis (Papers III–IV) explores the genetic architecture of complex diseases using our in-house cohorts. In Paper III, we explored the survival effects of the expression quantitative trait loci (eQTLs). Firstly, we identified 805 eGenes and 4,558 cis-eQTLs in a Japanese kidney cancer cohort (n=100). Then, we validated these findings cross-ethnically using TCGA data (n=287) through comprehensive survival analyses across different allelic and covariate models, revealing regulatory variants with consistent effects on patient survival. Lastly, in Paper IV, we conducted an integrative genomic-transcriptomic study in a pediatric congenital heart disease (CHD) cohort. We have identified known pathogenic variants and found that rare missense variant burdens of CHD-associated genes were significantly enriched in CHD patients compared to controls. Transcriptomic analysis revealed shifts in oxidative phosphorylation and interferon signaling. Functional analysis of overlapping eGenes and differentially expressed genes (DEGs) highlighted involvement in small GTPase-mediated signaling and cytoskeleton organization, and integration of rare-variant burdens further identified high-confidence candidates.

In summary, this thesis demonstrates the complex impacts of rare and common variants on human health across both rare and complex disease contexts. By developing computational platforms to assist in identifying risk loci and leveraging genomic data to uncover novel potential drivers, this work aims to advance translational genetics and precision medicine.

Abstract [sv]

Genomik representerar det första lagret i den centrala dogmen, där variationer i genomet påverkar nedströms biologiska processer och slutligen formar human fenomik. Även om nästa generations sekvenseringsteknik (NGS) har genererat enorma mängder genomiska data, kvarstår betydande luckor i tillämpningen av genomik inom klinisk medicin och precisionsmedicin.

Den första delen av denna avhandling (Artikel I–II) fokuserar på utveckling av högpresterande plattformar för kliniska genomiska och forskningstillämpningar. I Artikel I utvecklade vi GenRiskPro, en plattform utformad för att förbättra samverkan mellan viktiga aktörer inom klinisk genetik, däribland sjukhus, forskningsanläggningar, kliniker och patienter. Plattformen prioriterar rapportering av genetiska riskvarianter för sällsynta sjukdomar och inkluderar verktyg för att identifiera farmakogenomiska (PGx) och livsstilsassocierade varianter som påverkar komplexa egenskaper. Vi påvisade även populationsspecifik genetisk heterogenitet i anrikningen av patogena varianter och varianter med låg till sällsynt frekvens, vilka ofta uppvisar låg penetrans i sina fenomiska manifestationer.

I Artikel II utvecklade vi OncoRisk, en omfattande webbserver som integrerar flera kunskapsbaser inom precisionsonkologi samt pan-cancerkohort-data. Servern består av fyra huvudmoduler. Den möjliggör sökning av centrala onkogena termer såsom mutationer, genfusioner, sjukdomar och terapier, samt stödjer analys av individuella tumörsekvenseringsdata för att identifiera potentiellt betydelsefulla mutationer genom kartläggning mot kända onkogena resurser. Vi utvecklade även funktioner för snabb visualisering och analys av cancerkohortsdata samt för sökning av mutationsfrekvenser för specifika gener eller varianter i storskaliga cancersekvenseringskohorter.

Den andra delen av avhandlingen (Artikel III–IV) utforskar den genetiska arkitekturen hos komplexa sjukdomar med hjälp av våra egna kohorter. I Artikel III undersökte vi överlevnadseffekterna av expressionskvantitativa traitloki (eQTL). Vi identifierade inledningsvis 805 eGener och 4 558 cis-eQTL i en japansk njurcancerkohort (n=100). Därefter validerade vi dessa fynd tväretniskt med hjälp av TCGA-data (n=287) genom omfattande överlevnadsanalyser över olika alleliska och kovariat-modeller, vilket påvisade regulatoriska varianter med konsekventa effekter på patientöverlevnad.

I Artikel IV genomförde vi en integrativ genomisk-transkriptomisk studie i en pediatrisk kohort med medfödd hjärtsjukdom (CHD). Vi identifierade kända patogena varianter och fann att bördan av sällsynta missense-varianter i CHD-associerade gener var signifikant anrikad hos CHD-patienter jämfört med kontroller. Transkriptomisk analys påvisade förändringar i oxidativ fosforylering och interferonsignalering. Funktionell analys av överlappande eGener och differentiellt uttryckta gener (DEG) belyste deras involvering i liten GTPas-medierad signalering och cytoskelettonisering, och integration av sällsynta variantbördor identifierade ytterligare högkonfidens-kandidater.

Sammanfattningsvis belyser denna avhandling de komplexa effekterna av sällsynta och vanliga varianter på människors hälsa inom både sällsynta och komplexa sjukdomskontexter. Genom att utveckla beräkningsplattformar för att underlätta identifiering av riskloki och utnyttja genomiska data för att upptäcka nya potentiella drivande faktorer, syftar detta arbete till att främja translationell genetik och precisionsmedicin.
