The number of corrected FA phenotype corresponding to the sum of all samples (FA, FAC, FAE, FAO-Arab, FAD, FAKorle-Bu, FAX, FC, FE, FO Arab where either β^A gene was duplicated [β^Aβ^A] or associated with other β chain variants (β^Aβ^C, β^Aβ^E, β^Aβ^O-Arab, β^Aβ^D, β^Aβ^C, β^Aβ^X) or where duplicate ß chain variants were found (β^Cβ^C, β^Eβ^E, β^{O Arab}β^O-Arab) that are detected FA by MALDI. The number of corrected FAS phenotype corresponding to the sum of all heterozygous (FAS) and composite heterozygous (FSC, FSE, FSO-Arab) samples where βS gene was associated respectively to βA gene or to other ß chain variants (β^Sβ^C, β^Sβ^E, β^Sβ^O-Arab) that are detected FAS by MALDI.
