β-Thalassemia Trait Caused by SUPT5H Defects: Another Case Report.

We identified a novel mutation in the gene in a Chinese female who presented with a β-thalassemia trait. The substitution of c.193C > T (p.Arg65*) leads to a premature stop codon on residue 65 and could be associated with haploinsufficiency. This variant was inherited from the mother who also had the asymptomatic phenotype of β-thalassemia trait. Our case further supports the role of as a potential β-globin chain production-modulating gene.
