Taking over the Atlas
Dear Colleagues,
The Atlas, once more, is in great danger, and I will have to proceed to a collective economic lay-off of all the team involved in the Atlas before the begining of April 2015 (a foundation having suddenly withdrawn its commitment to support the Atlas). I ask you herein if any Scientific Society (a Society of Cytogenetics, of Clinical Genetics, of Hematology, or a Cancer Society, or any other...), any University and/or Hospital, any Charity, or any database would be interested in taking over the Atlas, in whole or in part. If taking charge of the whole lot is too big, a consortium of various actors could be the solution (I am myself trying to find partners). Could you please spread the information, contact the relevant authorities, and find partners.
Survival of the Atlas will be critically dependant upon your ability to find solutions (and urgently!).
Kind regards.
Jean-Loup Huret
Donations are also welcome
If each casual visitor gives 3 Euros or Dollars, the Atlas is saved in a week !
If each professional gives 100 Euros or Dollars once a year (now), the Atlas is saved in 2 weeks !
Don't let the Atlas imminent demise
Note: we send fiscal receipts for donations equal or above 50 Euros or Dollars

Description 14 exons; 1869 bp open reading frame
Transcription 2.2 and 2.5 kb


Description 622 amino acids, 69 kDa; contains a leucine zipper; can be phosphorylated
Expression weak; testis, thymus, lymphoblasts.
Localisation predominantly nuclear
Function part of the FA complex with FANCA, FANCC, FANCE, and FANCF; this complex is only found in the nucleus.
  • FANCA and FANCG form a complex in the cytoplasm, through a N-term FANCA (involving the nuclear localization signal) - FANCG interaction; FANCC join the complex; phosphorylation of FANCA would induce its translocation into the nucleus.This FA complex translocates into the nucleus, where FANCE and FANCF are present; FANCE and FANCF join the complex. The FA complex subsequently interacts with FANCD2 by monoubiquitination of FANCD2 during S phase or following DNA damage. Activated (ubiquinated ) FANCD2, downstream in the FA pathway, will then interact with other proteins involved in DNA repair, possibly BRCA1; after DNA repair, FANCD2 return to the non-ubiquinated form.
  • Homology no known homology


    Germinal wide range of mutations (splice, nonsense, missense)

    Implicated in

    Entity Fanconi anaemia (FA); FANCG is implicated in the FA complementation group G; it represents about 10% of FA cases.
    Disease Fanconi anaemia is a chromosome instability syndrome/cancer prone disease (at risk of leukaemia and squamous cell carcinoma)
  • Fanconi anaemia's prognosis is poor; mean survival is 20 years: patients die of bone marrow failure (infections, haemorrhages), leukaemia, or solid cancer.
  • It has recently been shown that significant phenotypic differences were found between the various complementation groups. FA group G patients had more severe cytopenia and a higher incidence of leukemia. FA group G patients patients are high-risk groups with a poor hematologic outcome and should be considered as candidates both for frequent monitoring and early therapeutic intervention.
  • Cytogenetics Spontaneously enhanced chromatid-type aberrations (breaks, gaps, interchanges; increased rate of breaks compared to control, when induced by specific clastogens known as DNA cross-linking agents (e.g. mitomycin C, diepoxybutane).
