Hb Coventry	beta141(H19)Leu->0 (probably incorrect:
	Suggested Leu->Hydroxyleu)

HEMATOLOGY		No hematological abnormalities
ELECTROPHORESIS		No separation of Hb X and Hb A
CHROMATOGRAPHY		No separation reported
STRUCTURE STUDIES		pCMB; tryptic digestion; separation of peptides by fingerprinting or HPLC; amino acid analysis; sequencing
DNA ANALYSES		Not reported
FUNCTION STUDIES		Increased oxygen affinity?
STABILITY		Unstable
OCCURRENCE		Found in several families and is widespread
OTHER INFORMATION		The Hb Coventry anomaly always occurs in association with another unstable Hb (Hb Sydney, Hb Atlanta); it is likely incorrectly identified as a deletion of leucine at beta141; more likely is oxidation to hydroxyleucine [see Hb Atlanta; beta75 (E19)Leu->Pro]
