Abstract

BACKGROUND: Faisalabad is the third biggest city of Pakistan. Majority of the population is Punjabi while other ethnic groups are in minority. AIMS: The present study was undertaken to find the mutations causing β-thalassemia in Faisalabad Pakistan. MATERIALS AND METHODS: A total of 285 β-globin alleles from 143 unrelated families having at least one transfusion-dependent child were analyzed by using amplification refractory mutation system (ARMS-PCR). RESULTS: FSC-8/9 (+G) and IVS-I-5 (G→C) were the most common mutations. The allele frequency for FSC-8/9 (+G) was 38.59% while frequency for IVS-I-5 (G→C) was 37.89%. The high frequency (76.48%) of IVS-I-5 (G→C) and FSC-8/9 (+G) on various alleles provides a strong evidence of intermarriages. CONCLUSIONS: By using ARMS-PCR, the mutations were successfully characterized in 95.79% of subjects, while 4.21% remain to be characterized. This study will facilitate the implementations of genetic counseling and prenatal diagnosis in the population of Faisalabad.
