Fanconi anemia (FA) is a rare autosomal recessive or X-linked disorder characterized by aplastic anemia, cancer susceptibility and cellular sensitivity to DNA-crosslinking agents. Eight FA proteins (FANCA, -B, -C, -E, -F, -G, -L and -M) and three non-FA proteins (FAAP100, FAAP24 and HES1) form the FA nuclear core complex that is required for monoub...
La préservation d’un stock de cellules souches fonctionnelles est indispensable pour le maintien de nombreux tissus chez l’adulte. Les cellules souches se multiplient pour s’auto-renouveller et entrent en différenciation donnant naissance à des progéniteurs puis à des cellules matures. Récemment, la possibilité pour les progéniteurs de se reprogram...

Nonerythroid α-spectrin (αIISp) is a structural protein involved in repair of DNA interstrand cross-links and is deficient in cells from patients with Fanconi anemia (FA), which are defective in ability to repair cross-links. In order to further demonstrate the importance of the role that αIISp plays in normal human cells and in the repair defect i...

The FANCJ family of DNA helicases is emerging as an important group of proteins for the prevention of human disease, cancer, and chromosomal instability. FANCJ was identified by its association with breast cancer, and is implicated in Fanconi Anemia. Proteins with sequence similarity to FANCJ are important for maintenance of genomic stability. Muta...
Fanconi anemia is a rare hereditary disease showing genetic heterogeneity due to a variety of mutations in genes involved in DNA repair pathways, which may lead to different clinical manifestations. Phenotypic variability makes diagnosis difficult based only on clinical manifestations, therefore laboratory tests are necessary. New advances in molec...

The Caenorhabditis elegans ortholog of the Fanconi anemia pathway component J (FANCJ) is DOG-1, which is essential for genome stability. Previous studies have shown that disruption of the dog-1 gene generates small deletions of poly-C/poly-G tracts detectable by PCR and results in a mutator phenotype. In this paper, we describe the isolation and ch...

ObjectiveFanconi anemia (FA) is a rare inherited genomic instability syndrome and usually associated with endocrine dysfunctions. We aimed to assess the diagnostic standards of chromosomal instability in FA and to correlate the breakage frequency with the severity of endocrinal dysfunctions.MethodsTwenty seven FA patients were randomly selected fro...

The rare genetic disorder Fanconi anemia, caused by a deficiency in any of at least thirteen identified genes, is characterized by cellular sensitivity to DNA interstrand crosslinks and genome instability. The excision repair cross complementing protein, ERCC1, first identified as a participant in nucleotide excision repair, appears to also act in ...

Homozygous loss of activity at the breast cancer-predisposing genesBRCA1 andBRCA2 (FANCD1) confers increased susceptibility to DNA double strand breaks, but this genotype occurs only in the tumor itself, following loss of heterozygosity at one of these loci. Thus, if these genes play a role in tumor etiology as opposed to tumor progression, they mu...

Designing stem cell transplantation (SCT) conditioning regimens for Fanconi anemia (FA) has proved difficult because of hypersensitivity to the DNA cross-linking agents. We performed chromosome fragility tests with 56 FA patients and with 50 non-FA patients with severe aplastic anemia or myelodysplastic syndrome. We evaluated peripheral blood lymph...
