" /> Fanconi anemia, complementation group o - CISMeF





Preferred Label : Fanconi anemia, complementation group o;

Symbol : FANCO;

CISMeF acronym : FANCO;

Type : Phenotype, molecular basis known;

Description : Fanconi anemia (FA) is a clinically and genetically heterogeneous disorder that causes genomic instability. Characteristic clinical features include developmental abnormalities in major organ systems, early-onset bone marrow failure, and a high predisposition to cancer. The cellular hallmark of FA is hypersensitivity to DNA crosslinking agents and high frequency of chromosomal aberrations pointing to a defect in DNA repair (summary by Deakyne and Mazin, 2011). For additional general information and a discussion of genetic heterogeneity of Fanconi anemia, see 227650.;

Inheritance : Autosomal recessive;

Molecular basis : Caused by mutation in the C homolog of the S. cerevisiae RAD51 gene (RAD51C, 602774.0001);

Laboratory abnormalities : Increased chromosomal breaks in response to cross-linking agents and ionizing radiation; Defect in DNA repair; Cellular arrest at G2 of the cell cycle;

Prefixed ID : #613390;
