Fanconi Anemia

Fanconi anemia (FA) is a rare inherited disorder characterized by defective DNA repair, leading to bone marrow failure, congenital? abnormalities, and cancer susceptibility. Patients typically present in childhood with progressive pancytopenia?, short stature, and skin hyperpigmentation. FA arises from pathogenic variants in at least 23 FANCA–FANCT genes, causing genomic instability and impaired hematopoiesis NCBIMedscape.

Types of Fanconi Anemia

Fanconi anemia is divided into genetic “complementation groups” based on which of the FA pathway genes is mutated. To date, more than 20 genes (now at least 23) have been identified—each corresponding to a complementation group designated FA‑A, FA‑B, FA‑C, and so on—encoding proteins that work together in the FA core complex to detect and repair DNA damage. The most common groups are FA‑A (FANCA gene), FA‑C (FANCC), and FA‑G (FANCG), together accounting for about 80–90 percent of FA cases. Mutations in any FA core complex gene prevent activation of downstream repair proteins (FANCD2 and FANCI), impairing the removal of DNA interstrand cross‑links and leading to the characteristic bone marrow failure and physical manifestations of FA MedlinePlus.

Causes

Fanconi anemia is caused by inherited mutations in genes of the FA pathway that compromise DNA repair. Below are 20 such genetic causes, each described in simple terms:

1. FANCA mutation
   A change in the FANCA gene disrupts production of the FANCA protein, a key part of the FA core complex. Without it, cells cannot properly repair DNA cross‑links, leading to bone marrow failure and congenital abnormalities MedlinePlus.

2. FANCB mutation
   Mutation in FANCB prevents formation of the core complex in cells, particularly impacting DNA repair in boys (X‑linked), since they have only one X chromosome MedlinePlus.

3. FANCC mutation
   Changes in FANCC reduce core complex stability, causing increased DNA breakage under stress and resulting in aplastic anemia and developmental defects MedlinePlus.

4. FANCD2 mutation
   Alterations in FANCD2 hinder its activation and recruitment of repair proteins, blocking interstrand cross‑link removal and causing rapid cell death in bone marrow MedlinePlus.

5. FANCE mutation
   E variants in FANCE destabilize the core complex, impairing repair of routine DNA damage and leading to FA symptoms MedlinePlus.

6. FANCF mutation
   Changes in FANCF prevent assembly of the FA core complex, making cells hypersensitive to DNA‑damaging agents MedlinePlus.

7. FANCG mutation
   A FANCG mutation disrupts a scaffolding protein essential for core complex integrity, resulting in faulty DNA repair and FA manifestations MedlinePlus.

8. FANCI mutation
   Alterations in FANCI stop its binding to FANCD2, halting recruitment of repair proteins and leading to DNA damage accumulation MedlinePlus.

9. FANCL mutation
   Changes in FANCL impair its E3 ubiquitin ligase activity, preventing activation of FANCD2/FANCI and causing DNA repair failure MedlinePlus.

10. FANCM mutation
    FANCM mutations reduce DNA damage sensing and recruitment of the FA core complex, causing elevated chromosome breakage MedlinePlus.

11. BRCA2 (FANCD1) mutation
    Mutations in BRCA2, also known as FANCD1, compromise homologous recombination repair and increase FA severity with high leukemia risk MedlinePlus.

12. BRCA1 mutation
    BRCA1 defects impair both FA pathway and breast cancer–related repair, leading to combined FA and cancer predisposition MedlinePlus.

13. PALB2 mutation
    PALB2 variations disrupt its role in FANCD2 recruitment, impairing cross‑link repair and raising FA and breast cancer risk MedlinePlus.

14. RAD51C mutation
    Changes in RAD51C interfere with strand invasion during DNA repair, causing chromosome instability seen in FA MedlinePlus.

15. BRIP1 (FANCJ) mutation
    BRIP1 (FANCJ) alterations hinder helicase activity needed for repair, leading to DNA cross‑link sensitivity and FA symptoms MedlinePlus.

16. ERCC4 (FANCQ) mutation
    ERCC4 defects block endonuclease recognition of cross‑links, preventing incision and repair MedlinePlus.

17. RAD51 mutation
    RAD51 changes impair recombination repair, causing heightened chromosome breakage under stress MedlinePlus.

18. MAD2L2 (FANCV) mutation
    Mutations in MAD2L2 affect the stabilization of stalled replication forks, leading to genome instability MedlinePlus.

19. RFWD3 (FANCW) mutation
    RFWD3 variants disrupt ubiquitin signaling at DNA damage sites, preventing proper repair MedlinePlus.

20. UBE2T (FANCT) mutation
    UBE2T defects impair ubiquitin conjugation needed for FANCD2 activation, blocking repair of DNA cross‑links MedlinePlus.

Symptoms

2. Frequent infections
