Hereditary spherocytosis (HS) is a common inherited anaemia characterized by the presence of spherocytic red cells and by a heterogeneous nature in terms of its clinical presentation, molecular basis and inheritance. Defects in several membrane protein genes have been involved in the pathogenesis of HS, including defects in the beta-spectrin gene. We detected a novel frameshift mutation in the beta-spectrin gene, a C deletion at codon 638, in a patient presenting with HS and spectrin deficiency. The mutant protein was not detected in the membrane or in other cellular compartments, but detectable levels of mutant mRNA were found in the patient. Interestingly, this mutation was not present in the patient's parents, suggesting a genetic mosaicism, especially as the patient has an affected brother with the same molecular defect. We analysed DNA from different tissues of the parents and the mutation was absent from all tissues analysed. This mutation seems to be confined to the germ cell lineage of the patient's mother and must present a mosaic pattern in these cells as the patient also has unaffected siblings.
