We have studied three compound heterozygotes for Hb Lepore (''Pylos'')
/HbS hemoglobin, a combination quite uncommon in the literature. It is
of interest that while two of these cases are clinically similar to t
hose thus far reported, the third one is free of symptoms and the diag
nosis was put incidentally, This mild condition may be due to the high
level of fetal hemoglobin produced. (C) 1995 Wiley-Liss, Inc.
