Report of SLC3A1/rBAT gene mutations in Iranian cystinuria patients: A direct sequencing study

Background: Considering a few studies on the genetic basis of the cystinuria in the Middle East and the population-specific distribution of mutations in the SLC3A1, we tried to find genetic variants in three exons (1, 3, and 8) of SLC3A1. Materials and Methods: In this study, exons 1, 3, and 8 of SLC3A1 gene of 25 unrelated cystinuria patients searched for genetic variations by polymerase chain reaction and sequencing. Results: There were five different variations in our studied population. We found one mutation in the SLC3A1 gene including missense variant M467K and identified three polymorphisms: nonsynonymous variant G38G, c. 610 + 169C>T and c. 610 + 147C>G within the SLC3A1 gene, and one new variant. Conclusion: Our results confirm that cystinuria is a heterogeneous disorder at the molecular level and more studies are needed to identify the distribution and frequency of mutations causing cystinuria in the Iranian population.
