Comments: This variant has been previously described in a Japanese woman in combination with a second mutation in exon 3 of the same β-globin gene. The variant associating the two mutations was named Hb Kochi [β141(H19)Leu>Val (c.424C>G) ; 144>146(HC1)Lys-Tyr-His->0 (c.433A>T)]. In the double variant hemoglobin, the β141(H19) Leu>Val mutant was initially thought to have no contribution in the Hb affinity disorder, a conclusion which is not supported by the description of this variant.
