A HindIII RFLP and a gene lesion in the coagulation factor VIII gene

Hum Genet. 1988 Apr;78(4):359-62. doi: 10.1007/BF00291736.


The presence and inheritance of restriction fragment length polymorphisms (RFLPs) and gene lesions in the coagulation factor VIII gene were investigated in 15 hemophilia families. An abnormal HindIII 2.6-kb band, previously detected in a severe hemophiliac, was observed in a not severely affected patient and also in the normal gene of a woman carrying a hemophilic gene in which the lesions was found. The TaqI site in exon 24 of this defective gene was removed by a C to T transition causing an amino acid change (Arg----Gln). Very low amounts of factor VIII activity and antigen were detected in the severely affected grandson. The presence of the HindIII 2.6-kb fragment in both normal and pathological genes indicates that a factor VIII RFLP without functional meaning was found. Its frequency, determined in 60 chromosomes, is 0.18. Double digestions enabled us to map the polymorphic site 3' to the exon 19.
