RT Journal Article SR Electronic T1 G gamma delta beta thalassaemia and g gamma HPFH (Hb Kenya type): comparison of 2 new cases. JF Journal of Medical Genetics JO J Med Genet FD BMJ Publishing Group Ltd SP 237 OP 244 DO 10.1136/jmg.14.4.237 VO 14 IS 4 A1 W G Wood A1 J B Clegg A1 D J Weatherall A1 O H Gyde A1 D A Obeid A1 M J Tarlow A1 M J Brown A1 S Hewitt YR 1977 UL http://jmg.bmj.com/content/14/4/237.abstract AB Two new cases of G gamma delta beta thalassaemia and G gamma HPFH (Hb Kenya type) have been characterised in detail and compared with regard to haematological data, globin chains biosynthesis, and intracellular distribution of Hb F. The similarities and differences between these two conditions are discussed in relation to the possible underlying defects at the molecular level and to the control of the gamma delta beta gene complex in general.
