Implication

Randomized trial evaluates prevalence and genetic characteristics of δβ-thalassemia and HPFH in women, highlighting regional specifics for genetic counseling.

Key Points

The study aims to define the molecular epidemiological features of δβ-thalassemia and HPFH in Quanzhou's childbearing-age population.
Cohort of 19,154 individuals underwent pre-pregnancy thalassemia screening.
DNA analysis included gap-PCR, PCR-reverse dot hybridization, and Sanger sequencing.
The correlation of hematological parameters with genotypes was analyzed.
Detection rate of deletion-type HPFH/δβ-thalassemia was 0.063% (12/19154), primarily SEA-HPFH and Chinese type Gγ+(Aγδβ)0.
Detection rate of γ-globin gene mutations and non-deletion-type HPFH was 0.329% (63/19154).
Identified 9 different γ-globin promoter mutations, with three key variants highlighted for their functional relevance.
