| Summary: | Five hundred pregnant women were analyzed for the presence of alpha-thalassemia-1 of the Southeast Asian (SEA)-type by polymerase chain reaction (PCR) technique at the Maharaj Nakhon Chiang Mai University Hospital in Chiang Mai during the period from April to June 1995. Forty-four of them (8.8%) were recognized as carriers, corresponding to a frequency of 0.044. Homozygous alpha-thalassemia-1 of the SEA-type, the fatal condition of hemoglobin Bart's hydrops fetalis, has an expected frequency of 0.00194, or about 2 hydrops fetalis cases per 1,000 births in this population. |
