Summary

A total of 2363 Cuban newborns were screened for genetic hemoglobin abnormalities; 2187 (92.56%) had a normal electrophoretic pattern. Of the 176 samples with abnormal electrophoretic patterns, 102 (4.32%) had hemoglobins A, F plus Bart's; 54 (2.29%) had hemoglobins A, F and S; 3 (0.13%) had hemoglobins A, F, S plus Bart's; 14(0.59%) had hemoglobins A, F and C; 1 (0.04%) had hemoglobins A, F, C and Bart's. The frequency of Hb Bart's was 4.46% in AA phenotype, 5.25% in AS, and 6.67% in AC. Two newborns were found to have rare variants. A close correlation was found between the observed and expected phenotypes, which indicates the accuracy of the diagnostic methods used. The results of all hemoglobin abnormalities were entered on the infants' hospital records. In addition, these families received genetic counseling.
