Overview

Fanconi anemia is currently classified by complementation group.

Classification

Fanconi anemia is a heterogenous disease from a genetic standpoint. Fanconi anemia is currently classified by complementation group. The four subtypes of Fanconi anemia can be discerned by somatic cell hybridization studies.^[1] This concept is based on the fact that at least four different genes function in concert to support normal hematopoiesis in healthy persons.^[1] The four subclasses of Fanconi anemia are:

FA-A
FA-B
FA-C: This class of Fanconi anemia is characterized by a gene that encodes for a protein with unknown function, though it is known to localize to the cytoplasm. Six variants have been found in FA-C, and these are associated with disease.^[1] Approximately 8% of people with Fanconi anemia belong to complementation group C.
FA-D
