Molecular Diagnosis of Solute Carrier Family 4 Member 1 (SLC4A1) Mutation–Related Autosomal Recessive Distal Renal Tubular Acidosis
2019
Background: Two common mutations of the solute carrier family 4 member 1 (SLC4A1) gene, namely, Southeast Asian ovalocytosis (SAO) and band 3 Bangkok 1 (G701D), cause autosomal recessive distal renal tubular acidosis (AR dRTA) in ethnic Southeast Asian populations. In this study, we applied the high-resolution melting (HRM) method for screening of AR dRTA associated with SLC4A1 mutations in 10 new patients with unknown cause(s) of AR dRTA. Methods: We analyzed SAO and G701D mutations in the patients and their family members using HRM. The results were confirmed by polymerase chain reaction-restriction fragment-length polymorphism (PCR-RFLP) and DNA sequencing techniques. Results: All patients carried homozygous G701D mutation, whereas their family members had heterozygous G701D or homozygous wild-type. Conclusions: Homozygous G701D is a common cause of AR dRTA in ethnic Thai pediatric populations. HRM can be used as a rapid screening method for common SLC4A1 mutations that cause AR dRTA in Southeast Asian and other populations.
