A systematic framework for selecting gene-condition pairs for inclusion in newborn sequencing panels: Early Check implementation.

Research is underway worldwide to investigate the feasibility, acceptability, and utility of sequencing-based newborn screening. Different methods have been used to select gene-condition pairs for screening, leading to highly inconsistent gene lists across studies. Early Check developed and utilized actionability-based frameworks for evaluating gene-condition pairs for inclusion in newborn panels (Panel 1 - high actionability, Panel 2 - possible actionability). A previously developed framework, the Age-based Semi Quantitative Metric (ASQM), was adapted. Increasing ASQM scores, with a maximum of 15, suggest greater actionability. Wilcoxon tests were performed to compare Panel 1 gene-condition pairs on the Recommended Uniform Screening Panel (RUSP) to non-RUSP pairs. In our first round of assessment, Early Check identified 178 gene-condition pairs for inclusion in Panel 1 and 29 for Panel 2. Median ASQM scores of RUSP conditions on Panel 1 was 12 (range 4 to 15) and non-RUSP was 13 (range 9 to 15). Median scores for Panel 2 was 10 (range 6 to 14). The Early Check frameworks provide a transparent, semiquantitative, and reproducible methodology for selecting gene-condition pairs for NBS sequencing pilot studies that may inform future integration of genomic sequencing into population-level NBS. Collaborative efforts among newborn sequencing studies to establish shared criteria is needed to enhance cross-study comparisons.
