Overview

Randomized trial evaluates SMRT sequencing to improve diagnosis and genetic counseling accuracy in α-thalassemia.

Key Points

  • The study evaluates the effectiveness of single-molecule real-time sequencing in diagnosing complex α-thalassemia variants.
  • Enrolled 9180 individuals from January 2023 to April 2025 in Dongguan.
  • Conducted routine thalassemia genetic testing followed by SMRT sequencing of specific samples.
  • Utilized multiplex ligation-dependent probe amplification for comparative analysis.
  • SMRT sequencing distinguished difficult genotypes with high precision and identified benign and pathogenic variants.
  • Successfully revealed complex rearrangements that conventional methods often miss.
  • Reported a new genotype, −α 3.7 /αα12, in the Chinese population.
