Abstract

PURPOSE: Congenital hemolytic anemia caused by red blood cell (RBC) membrane defects is a heterogeneous group of disorders. The present study aimed to search the causative gene mutations in patients with RBC membrane disorders in Taiwan.
MATERIALS AND METHODS: Next-generation sequencing approach using whole-exome sequencing (WES) was performed. Sanger sequencing was performed for confirmation of variants detected in WES in patients and their family members.
RESULTS: Five causative variants, including two ANK1, two SPTA and one SPTB variants, were detected in four patients. All these variants, except one SPTA1 variant c.83G > A (p.R28H), are novel variants. Their pedigree analysis showed one de novo SPTA1 mutation c.83G > A (p.R28H) combined with αLELY, one de novo ANK1 mutation c.1034C > A (p.A345E), one autosomal dominant combined SPTA1 c.4604A > C (p.Q1535P) and SPTB c.6203 T > C (p.L2068P) mutations and one autosomal dominant ANK1 c.4462C > T (p.R1488X) mutation.
CONCLUSIONS: Our data demonstrated that WES is an efficient tool for determining genetic etiologies of RBC membrane disorders and can facilitate accurate diagnosis and genetic counseling. Additional studies should be conducted on larger cohorts to investigate the distribution of gene mutations in patients with RBC membrane disorders in Taiwan.
