ABSTRACT
Abstract Objective Data from DNA genotyping via a 96-SNP panel in study of 25,015 clinical samples were utilized for quality control and tracking sample identity sequencing network. The aimed to demonstrate the value both precise SNP utility predicting sex-by-genotype participants, identify possible mix-ups. Results Precise showed no swap errors within testing laboratories. In contrast, when comparing predicted provided sex on test requisition, we identified 110 inconsistencies (0.44%), that had occurred during collection or accessioning. genetic predictions confirmed using additional sites data high-density arrays. It was determined discrepancies resulted clerical (49.09%), transgender participants (3.64%) stem cell bone marrow transplant patients (7.27%) along with undetermined mix-ups (40%) which swaps prior arrival at genome centers, however exact cause events sampling resulting not able be determined.
