We report a new hemoglobin variant which we have named Hb Silver Sprin
gs. This variant results from a substitution CAG-->CAC (Gln-->His) at
codon 131 of the beta chain. It was detected only by cation exchange h
igh performance liquid chromatography. This is the fifth reported subs
titution at codon 131. This variant does not appear to have any clinic
al or hematologic manifestations.
