    Hemoglobin. 1981;5(2):139-51.

    Survey of cord blood hemoglobin in Japan and identification of two new gamma chain variants.

    Fuyuno K, Torigoe T, Ohba Y, Matsuoka M, Miyaji T.

    Two gamma chain variants were discovered during a survey of 2,569 cord bloods of Japanese. One was the first case with mutation of the T-gamma chain, i. e. Hb F Yamaguchi or gamma 80 (EF 4) Asp leads to Asn (75 Thr, 136 Ala). It comprised 33.6% of Hb F, an unusually high percentage for a gamma chain variant. The other concerned with the first report of substitution at E 16, i. e. Hb F Iwata or gamma 72 (E 16) Gly leads to Arg (75 Ile, 136 Ala). It comprised 11.0% which is comparable to the values usually reported in an A-gamma chain variant. No clinical consequences have been observed in association with the hemoglobin variants.
