(kun-JEH-nih-tul … sel uh-PLAY-zhuh)
A very rare disorder in which the bone marrow doesn’t make enough red blood cells. It is usually seen in the first year of life. Patients may have deformed thumbs and other physical problems.

Patients with congenital pure red cell aplasia may have a mutation (change) in one of the genes that make proteins found in the cell’s ribosomes.
