In the human DNA mismatch repair (MMR) system, hMSH2 forms the hMutSalpha and hMutSbeta complexes with hMSH6 and hMSH3, respectively, whereas hMLH1 and hPMS2 form the hMutLalpha heterodimer. These complexes, together with other components in the MMR system, correct single-base mismatches and small insertion/deletion loops that occur during DNA replication.(More)
Bannayan-Riley-Ruvalcaba syndrome (BRRS) is a rare hamartomatous polyposis condition with features of macrocephaly, intestinal juvenile polyposis, developmental delay, lipomas, and pigmentation spots of the male genitalia. An autosomal dominant pattern of inheritance exists in some families, but others appear as sporadic cases. Germ-line mutations in PTEN,(More)
