Presentation
Progressive bone marrow failure with pancytopenia typically presents in the first decade, often initially with thrombocytopenia or leukopenia. The incidence of acute myeloid leukemia is 13% by age 50 years. [ncbi.nlm.nih.gov]
Acronym FANCD2 Synonyms FA4 FACD FAD2 FANCD Fanconi anemia complementation group D Fanconi pancytopenia type 4 Keywords Any medical or genetic information present in this entry is provided for research, educational and informational purposes only. [uniprot.org]
Clinical presentation and biological confirmation of 7 FA patients identified are detailed, and strategies for a comprehensive and precise diagnosis of FA in patients presenting with BMF are discussed. [haematologica.org]
RESULTS: About 65% of SNPs and 55% of INDELs were found to be commonly present in both the FA dysfunctional and retrovirally corrected cell lines, showing their common origin. [cancerindex.org]
Malformations were present in 96% of cases and consisted mainly of skeletal malformations. Abnormal skin pigmentations were present in 92% of cases. The ages of patients ranged from 1 year to 30 years. The mean age at diagnosis was 9 years. [nature.com]

None of the mutant fish displayed gross developmental abnormalities except for fancp-/- fish, which were significantly smaller in length than their wildtype clutch mates. [cancerindex.org]

Microbiology
- Human Papillomavirus
Khanal S, Galloway DA High-risk human papillomavirus oncogenes disrupt the Fanconi anemia DNA repair pathway by impairing localization and de-ubiquitination of FancD2. [cancerindex.org]
Treatment
It is not in any way intended to be used as a substitute for professional medical advice, diagnosis, treatment or care. Our staff consists of biologists and biochemists that are not trained to give medical advice. [uniprot.org]
Since FA is itself a genetic disease, these data imply that patient genotype and/or transcriptome may impact the effectiveness of gene editing treatments and that treatments biased toward FA repair pathways could have therapeutic value. [cancerindex.org]
Following aphidicolin treatment, targets chromatid gaps and breaks. [antibodies.com]
If breaks are increased, a diagnosis of FA is made and appropriate treatment/follow-up offered. [haematologica.org]
Etiology
This included BMF patients (i) without any evidence of an associated underlying etiology, (ii) with only an isolated non-specific positive sign in history or physical examination (i.e. isolated short stature, or café-au-lait spots, or history of consanguinity [haematologica.org]

Prevention
For long term storage, store at -20°C in small aliquots to prevent freeze-thaw cycles. [anticorps-enligne.fr]
Plays a role in preventing breakage and loss of missegregating chromatin at the end of cell division, particularly after replication stress. [antibodies.com]
