The leftward deletion alpha-thal-2 haplotype in a black subject with
hemoglobin SS
SH Embury, MA Gholson, P Gillette and RF Rieder
We have identified a black individual with homozygous sickle cell anemia
who is the silent carrier of alpha-thalassemia (genotype - alpha/alpha
alpha) due to heterozygosity for the leftward deletion alpha-thal-2
haplotype. This deletion has not been described previously in a black
subject and is the only leftward deletion that we have found among 255
alpha-thal-2 chromosomes from sickle cell subjects. Its effects on the
clinical, hematologic, biosynthetic, and cellular pathology of sickle cell
anemia resemble those reported for the common alpha-thalassemia genotypes
of the black population.
