Abstract
Nucleotide sequence comparisons of the published cDNAs and genomic sequences coding for the gamma-chain of human fibrinogen revealed several differences. We isolated two independent human cDNA clones, coding for part of this protein and compared their sequences, which are identical with the published relevant data. Our sequence allowed us to solve a conflict for aminoacid 88. All the remaining differences resulting from this comparison occurred in the third position of a codon and did not change codon properties or restriction sites. The level of polymorphism of this gene is discussed, taking into account also the nucleotide differences among all the published relevant data.
