The gamma-chain structure of a homozygote for HPFH Negro type, previously described by Acquaye and co-workers, and of 3 heterozygotes of the same family has been evaluated. G gamma and A gamma chains were present in a ratio of fetal type (7/3) in the homozygote and in ratios of 2/3 and 1/1 in the heterozygotes, in agreement with data of the literature. T gamma chains were absent in all the cases. Our results, compared with those previously reported for Negro and Greek HPFH, suggest that the T gamma gene is never linked with the HPFH determinant.

Abstract
The gamma-chain structure of a homozygote for HPFH Negro type, previously described by Acquaye and co-workers, and of 3 heterozygotes of the same family has been evaluated. G gamma and A gamma chains were present in a ratio of fetal type (7/3) in the homozygote and in ratios of 2/3 and 1/1 in the heterozygotes, in agreement with data of the literature. T gamma chains were absent in all the cases. Our results, compared with those previously reported for Negro and Greek HPFH, suggest that the T gamma gene is never linked with the HPFH determinant.File in questo prodotto:
