Hb Dartmouth [alpha66(E15)Leu-->Pro (alpha2) (CTG-->CCG)]: a novel alpha2-globin gene mutation associated with severe neonatal anemia when inherited in trans with Southeast Asian alpha-thalassemia-1.

abstract：:Hb Taybe is a highly unstable hemoglobin (Hb) variant caused by a 3 bp deletion at codons 38/39 (-ACC) on the α1-globin gene. We report for the first time, a patient with a compound heterozygosity for Hb Taybe and a 5 bp deletion at the splice donor site of IVS-I on the α2-globin gene and ischemic stroke and priapism....
