MYH associated polyposis: severe phenotype in the homozygosity for the 1103delC...
De Ferro, Susana Mão; Lage, Pedro; Suspiro, Alexandra; Fidalgo, Paulo; Fragoso, Sofia; Baltazar, Célia; Vitoriano, Inês; Rodrigues, PaulaMYH-associated polyposis (MAP) is an autosomal recessive disease associated with multiple colonic adenomas and colorectal cancer. Y165C and G382D MYH missense mutations are involved in more than 80% of cases in Caucasians and the large series published do not include patients homozygous for other mutations. We present the report of two siblings homozygous for the nonsense frameshift mutation 1103delC. The proba...
