Detection of the band 3 gene mutation in HS patients. (A) SSCP analysis of the exon 8 and intron-exon boundaries showing a band shift in a patient with band 3 deficiency (patient II.2, lane 2). Samples applied on lanes 1, 3, and 4 belong to three unrelated patients with band 3 deficiency. (B) Direct sequencing of the PCR product showing a mutation in intron 8, position + 1G → T.
