We evaluated the loss of heterozygosity (LOH) at 10q(23.3) locus of microsatellite markers; D10S198, D10S192, and D10S541 of PTEN gene in 223 North Indian colorectal cancer (CRC) specimens. DNA was isolated and microsatellite-specific markers polymerase chain reaction was performed. Out of total 223 cases 102 showed LOH for at least one of the locus. In addition, thereto a significant association was found with the clinicopathologic features like grade of differentiation, clinical stage, invasion, lymph node invasion, and the clinical outcome (p<0.05). These data argue that the given markers to check the possible LOH of PTEN gene at locus 10q(23.3) could be considered as one of the diagnostic markers in CRC.
