In this study, we report two novel thalassemia variants detected in Chinese individuals using targeted NGS technology. We detected a novel frameshift variant, HBB: c.181delG, in a 32-year-old Chinese individual. This novel variant [a single nucleotide deletion at nucleotide 181 of codon 60 (-G)], was detected by targeted next generation sequencing (NGS), resulting in a stop codon at codon 60 in exon 2 of the HBB gene. The impact of this novel variant was further analyzed by an invitro model. We also identified a novel in-frame variant, HBA1: c.121_126delAAGACC [codons 40/41 (-AAGACC)], in another Chinese individual in this study. We named these two novel variants, HBB: c.181delG and HBA1: c.121_126delAAGACC according to the Human Genome Variation Society (HGVS), which were detected by the first author. These two novel variants have expanded the mutation spectrum of thalassemia and it would be beneficial for carrier screening, genetic counseling and prenatal diagnosis (PND) of thalassemia.
