Objective:

To evaluate the effectiveness of long-read whole genome sequencing (WGS) in identifying genetic variants linked to unexplained infertility and recurrent pregnancy loss.

Key Findings:
  • Pathogenic or likely pathogenic variants were identified in 4.8% of individuals.
  • Approximately one in 10 affected couples carried a clinically significant genetic variant.
  • Identified variants were linked to conditions such as premature ovarian insufficiency and spermatogenic failure.
  • The sequencing workflow achieved an average genome coverage depth of 34.6×.
Interpretation:

Limitations:
  • Balanced chromosomal rearrangements remain difficult to identify reliably with current long-read datasets.
  • Cost of long-read sequencing is still a barrier to broader clinical use.
Conclusion:
