Validation of (HBB:c.20A > T, p.Glu6Val) substitution. Sequences alignment of products using primers A-E corresponding to Exon 1, IVS-I, and Exon 2. The sequences for the HBB gene (NCBI RefSeq NG_059281.1), one control of a healthy individual, and the twelve HbAS individuals are depicted in the left panel. The vertical line in the electropherograms indicates the [A > T] substitution analyzed and corresponds to (a) Control of a healthy individual (HbAA). (b) Heterozygous Individual (HbAS) and (c) Control of homozygous individual (HbSS). W = A, T.
