OBJECTIVE: To detect disease-causing mutations in a patient with hereditary elliptocytosis.
METHODS: Sodium dodecyl sulfate polyacrylamide gel electropheresis (SDS-PAGE) was used to identify the type of erythrocyte membrane protein defect. Potential mutations of the exons and adjacent introns of relevant genes were analyzed by Sanger sequencing.
RESULTS: SDS-PAGE has failed to detect any difference between the patient and healthy controls. However, Sanger sequencing has detected three mutations in the SPTA1 gene in the patient, which included c.5077A>C (p.Lys1693Gln) missense mutation in exon 36, c.5572C>G (p.Leu1858Val) missense mutation in exon 40, and a IVS45nt-12C>T in intron 45. The father and grandmother of the patient were both heterozygous for c.5077A>C mutation, while her mother was heterozygous for c.5572C>G and IVS45nt-12C>T mutations.
CONCLUSION: The hereditary elliptocytosis in the patient may be attributed to the synergistic action of c.5077A>C, c.5572C>G and IVS45nt-12C>T mutations of the SPTA1 gene.
