摘要: Mutations in MCM9, which encodes DNA helicase, were recently shown to cause a clinical phenotype of primary ovarian failure and chromosomal instability. MCM9 plays an essential role homologous recombination-mediated double-strand break repair. We describe multiplex family with early colorectal carcinoma mixed polyposis associated hypergonadotropic hypogonadism. A combination whole genome homozygosity mapping as well exome sequencing targeted gene identified homozygous c.672_673delGGinsC mutation that predicts truncated protein, p.Glu225Lysfs*4. Our data expand the phenotypic spectrum mutations suggest link between inherited predisposition early-onset cancer.
