NCT06060184

Brief Summary

The study aims to comprehensively introduce Long-read Genome sequencing (LR-GS) based genetic testing into clinical routine. In order to demonstrate the superiority of untargeted LR-GS over Short-read Genome sequencing (SR-GS) to establish firm genetic diagnoses, the investigators will rely on a multi-center "Translate Nationale Aktionsbündnis für Menschen mit Seltenen Erkrankungen" (Translate National Action Alliance for People with Rare Diseases Germany, TNAMSE) cohort of unsolved patients with neurological, neurodevelopmental, and imprinting disorders that is expectedly enriched for complex genomic variation. Within the framework of genomDE, the investigators will then implement, for the first time, LR-GS in the diagnostic work-up of a prospective cohort of patients with a broad range of clinical indications including rare diseases and cancer predisposition.

Outcome Measures

Primary Outcomes (1)

  • Number of patients with Rare Disease (RD) or cancer predisposition syndromes with confirmed diagnosis by LR-GS compared to previous diagnostic methods including SR-GS

    A molecular diagnosis is considered confirmed when likely pathogenic or pathogenic variants are identified according to the American College of Medical Genetics and Genomics (ACMG). classification.

    Day 1

Study Arms (2)

Retrospective cohort

EXPERIMENTAL

Subjects with unclear molecular cause of the disease. The subjects are clinically characterized in the context of outpatient/ inpatient standard care at the University Hospital Tübingen (UKT) or cooperating locations.

Genetic: Next-Generation Sequencing (NGS)

Prospective cohort

EXPERIMENTAL

Subjects with indication for genome diagnostics (e.g. within the initiative for genomic medicine (genomDE) based on §64e German Social Code (SGB) Fifth Book (V) (SGB V).

Genetic: Next-Generation Sequencing (NGS)

Interventions

Sequencing of genomes (Long read NGS)
