Description

A rare autosomal recessive form of dyskeratosis congenita caused by biallelic mutations in the gene WRAP53. Only 3 unrelated families have been described so far. Clinical presentation is that found in dyskeratosis congenita: leukoplakia, bone marrow failure, hyperpigmentation and nail dystrophy.

Management

Surveillance (eg, with regularly performed CBC as well as other measures in the presence of concern for hematologic sequelae) for bone marrow failure, as well as surveillance for multiple cancer types (eg, with self-examination and clinical examination), and pulmonary disease may allow early detection and treatment. Lung transplant may be indicated in individuals with advanced lung diease. HSCT may be indicated due to manifestations including leukemia and bone marrow failure (which may also be treated with androgen therapy), but the long-term efficacy may not be optimal.
