MYH-associated polyposis (MAP) is an autosomal recessive inherited disease. People with MAP tend to develop multiple adenomatous colon polyps during their lifetime and have an increased risk of colorectal cancer. MAP has only recently been described and there is much to be learned about the condition. Recessively inherited mutations in the base excision repair gene MYH have recently been associated with predisposition to colorectal adenomas and cancer. The epidemiology of MYH-associated polyposis (MAP) is poorly known in populations with high levels of consanguinity like North African populations, in particular in Morocco, and the MAP carrier frequency in the general Moroccan population has never been evaluated. The present study was carried out among the Moroccan population, using molecular epidemiology methods, to estimate the prevalence of homozygote or compound heterozygote genotype conferring MAP due to three mutations reported as recurrent in MAP: c.494A>G (Y165C), c.1145G>A (G382D) and c.1186_1187insGG (p.Glu396fsX42).
