Diamond-Blackfan Anemia: 2 Cases With a Twist.

Background: Diamond-Blackfan anemia is a rare inherited bone marrow failure disease. Typical findings include hypoplastic macrocytic anemia, congenital anomalies, and a predisposition to cancer. The molecular basis of the disease is heterozygous mutations of ribosomal proteins without a strict correlation between genotype and phenotype.
Observation: We present 2 cases of Diamond-Blackfan anemia diagnosed during infancy with interesting clinical, molecular, and family characteristics.
Conclusions: A thorough evaluation of all family members is imperative to identify possible 'silent carriers' who are those with no physical stigmata and minor or absent hematologic manifestations. New mutations could add in the map of the disease.
Competing Interests: The authors declare no conflict of interest.
