MSP of p16INK4A gene: p16INK4A gene methylation pattern as viewed from left to right shows a 50-bp ladder as a molecular weight marker, a water control for contamination in PCR reaction, a methylated DNA band in patient 1, an unmethylated DNA band in patient 2, a heterozygous pattern (both methylated and unmethylated bands) in patients 3, and an unmethylated DNA band in a control sample
