This deletion has been reported in at least eight afibrinogenemic patients [34], and, together with other two gross deletions that are described in the FGA gene (i.e., a 15-kb and a 4.1-kb deletion) [30,35], account for ~9% of all cases of afibrinogenemia characterized by mutations in FGA [34]. This evidence concerns the gene FGA and Familial afibrinogenemia.
