Genetic heterogeneity in acatalasemia.
203 bp long products containing exon 4 and its junctions from the catalase gene were generated by polymerase chain reaction (PCR). These products were analyzed by single strand conformational polymorphism (SSCP), hetero-duplex formation and nucleotide sequencing. No polymorphism was detected when the Hungarian acatalasemic sisters, their family members and normocatalasemic controls were analyzed. Sequence analyses did not show the G to A point mutation at position 5 of intron 4. This splicing mutation characterizes the Japanese-type of acatalasemia.
