New clinical features of Fanconi anemia

Fanconi anemia performs (FA) great clinical heterogeneity. Although the identification of FA related genes extends the recognition of FA pathogenesis, few stringent genotype-phenotype connections have emerged. For the same FA genotype patients, it seems that type of mutation influences clinical phenotype more importantly, Modifier genes,environmental factor, can also result in obviously different clinical phenotype. Different from multiple genotypes and multiple clinical phenotypes, FA cellular phenotype is characteristic, and is the most important basis of diagnosis.
