Question
Scenario 1: Dyskeratosis congenita (DKC) is a rare human genetic disorder affecting
telomere replication. Mutations in the genes encoding telomerase enzymes result in
telomeres with RNA subunits that do not read 3'-CAACCCCAAC-5'. DKC symptoms
include bone marrow failure (reduced production of blood cells) and anemia. If
symptoms are severe, a bone marrow transplant may be the only form of effective
treatment.
