In Southeast Asia α-thalassaemia, β-thalassaemia, haemoglobin (Hb) E and Hb Constant Spring (CS) are prevalent. The abnormal genes in different combinations lead to over 60 different thalassaemia syndromes, making Southeast Asia the locality with the most complex thalassaemia genotypes. The four major thalassaemic diseases are Hb Bart's hydrops fetalis (homozygous α-thalassaemia 1), homozygous ...

The α-globin genes were studied in nine families with unexplained hypochromic anaemia and in 167 patients with HbE β thalassaemia in Sri Lanka. As well as the common deletion forms of α(+) thalassaemia three families from an ethnic minority were found to carry a novel form of α(0) thalassaemia, one family carried a previously reported form of α(0) thalassaemia, --(THAI), and five families had d...

Beta-thalassaemia is a hereditary defect in the synthesis of beta-polypeptide chains of haemoglobin. Most patients with beta-thalassaemia can be classified, both genetically and haematologically, into those with the homozygous form of the disease, and those with the heterozygous disease or thalassaemia minor. However, in clinical practice one occasionally encounters a patient with thalassaemia ...

During the past few years there have been several reports of thalassaemia occurring in English families (Garrett and Morton, 1960; Callender, Mallett, and Lehmann, 1961; Josse, 1962; Roberts, 1963). All the cases, however, have been of the heterozygous form of the disease (thalassaemia minor and thalassaemia trait). This paper reports the case of an English child with homozygous thalassaemia (t...

Both α- and β-thalassaemia syndromes are public health problems in the multi-ethnic population of Malaysia. To molecularly characterise the α- and β-thalassaemia deletions and mutations among Malays from Penang, Gap-PCR and multiplexed amplification refractory mutation systems were used to study 13 α-thalassaemia determinants and 20 β-thalassaemia mutations in 28 and 40 unrelated Malays, respec...

BACKGROUND Thalassaemia is a common public health problem in Malaysia and about 4.5 to 6% of the Malays and Chinese are carriers of this genetic disorder. The major forms of thalassaemia result in death in utero of affected foetuses (α-thalassaemia) or life-long blood transfusions for survival in β-thalassaemia. This study, the first nationwide population based survey of thalassaemia in Malaysi...

Thalassaemia is a common disorder in Malaysia. It is estimated that 4.5% of the population are carriers for beta- or alpha- thalassaemias. We set out to screen Form 4 students aged between 15 and 16 years old in a national school, for thalassaemia in March 2008. Written consent was obtained from 310 students. The carrier rate for the common thalassaemia syndromes was 6.8% (2.9% for beta-thalass...
