Molecular genetic diagnosis of beta thalassemia in Pakistan

A set of procedures, based on DNA analysis, has been developed to detect deletions and point mutations causing Beta thalassemia in the Pakistani population. These procedures can be used to analyze the presence of relevant changes in DNA, thus providing a reliable means for screening the high risk families, to provide them genetic counseling and prenatal diagnosis during early pregnancy. We have identified two mutations IVS-1 nt.5 [G--C] and codon 8-9 [+G] in 4 of the 6 families analysed for these mutations
