How the Fanconi anemia pathway guards the genome?

The Fanconi Anemia pathway is thought to coordinate a complex mechanism that enlists elements of three classic DNA repair pathways, namely homologous recombination, nucleotide excision repair, and mutagenic translesion synthesis, in response to genotoxic insults.

What is difference between Fanconi syndrome and Fanconi anemia?

Fanconi anemia is a rare disease passed down through families (inherited) that mainly affects the bone marrow. It results in decreased production of all types of blood cells. This is the most common inherited form of aplastic anemia. Fanconi anemia is different from Fanconi syndrome, a rare kidney disorder.
