Infrequent genetic alterations of p53, p16 genes and polymorphism in fhit gene in Indian myelodysplastic syndrome.

Alterations in the tumor suppressor genes p53, p16, and fhit were studied in myelodysplastic syndrome (MDS) samples of Indian patients. PCR-SSCP analysis showed evidence for the presence of polymorphism in fhit gene in 7 of 15 samples. We failed to get any evidence for mutation in the p53, p16, and fhit genes. These results indicate that mutational inactivation of these genes may not play a major role in the development of myelodysplastic syndrome.
