Congenital afibrinogenemia is a rare autosomal recessive disorder characterized by the complete absence of detectable fibrinogen. We previously identified the first causative mutations for this disease, these were homozygous deletions of approximately 11 kb of the fibrinogen alpha chain gene (FGA). Subsequent analyses revealed that the great majority of afibrinogenemia alleles are truncating mutations of FGA, although mutations in all three fibrinogen genes, FGG, FGA and FGB have been identified. In this study, we performed the first prenatal diagnosis for afibrinogenemia. The causative mutation in a Palestinian family was a novel nonsense mutation in the FGB gene, W467X. Expression of the W467X mutant FGB cDNA in combination with wild-type FGA and FGG cDNAs showed that fibrinogen molecules containing the mutant beta-chain are not secreted into the media. The fetus was found to be heterozygous for the W467X mutation by direct sequencing and by linkage analysis, a result which was confirmed in the new-born by intermediate fibrinogen levels.
