Study to Compare Traditional and Emerging Methods for Structural Variant Analysis in Prenatal, Postnatal, and Hematologic Samples
Multicenter Performance Study Using a Non-CE-marked in Vitro Diagnostic Medical Device (IVD) for the Standardization and Comparative Evaluation of Traditional and Emerging Methods for the Analysis of Structural Variants in Prenatal, Postnatal, and Oncohematological Samples
The study goal is to evaluate an innovative technology, KaryoSolver, which enables molecular karyotype reconstruction, in comparison with reference conventional methods, in terms of:
Presence or absence of clinically detectable structural variants; Type of alteration (aneuploidies, deletions, duplications); Copy number present. KaryoSolver is a software system for reconstructing the molecular karyotype from low-coverage genomic sequencing data using long-read technology.
The expected performance of the device under study is its ability to detect and classify the main clinically detectable structural variants within included samples in a manner consistent with the reference comparators, using a standardizable workflow, competitive turnaround times, and adequate reproducibility.
연구 개요
상세 설명
In particular, the study contributes to demonstrating the following requirements:
- scientific validity, through the correlation between Karyosolver and the aCGH/SNP array result used as a reference;
- analytical performance, including accuracy, analytical sensitivity, analytical specificity, and reproducibility of the method, evaluated according to the criteria defined by ISO 5725;
- clinical performance, through the evaluation of the test's ability to correctly identify copy number variations (CNVs) or regions of loss of heterozygosity (LOH/ROH) already reported in the samples selected for the study.

연구 인구
The biological samples are residual samples already available at the two participating clinical centers. The samples originate from diagnostic workups that have already been completed and were not collected specifically for this study. In particular, residual samples related to prenatal, postnatal constitutional, and oncohematological diagnostics may be used, in accordance with the criteria set forth in the protocol.

IPD 계획 설명
IPD will not be shared because this is a non-interventional study which does not produce any health outcomes; it is, in fact, a performance study involving IVDs conducted solely for methodological research purposes, with no results being reported for diagnostic or therapeutic purposes.
