Revesz syndrome (RS) is a rare genetic disease. It is generally regarded in literature as a less commonly occurring, more severe, variant of dyskeratosis congenita (DC). Thus the former exhibit features that are typical of DC, such as abnormal nail formation, skin hyperpigmentation, and oral leukoplakia [1]. RS occurs as a result of genetic mutation, specifically in the TINF2 gene coding for a protein that is involved in telomere synthesis. The same gene has been found to be responsible for some forms of DC.

The phenotypic features of RS have not been fully delineated, as there is a small number of reported cases, amongst which there is great variation in clinical presentation [2] [3].

Features that are typical of RS include ocular and periorbital abnormalities such as lid deformities, exudative retinopathy, vitreous hemorrhage, corneal or vitreous opacification, and conjunctival scarring. These features manifest in childhood and may cause a decrease in visual acuity, or blindness. Within the central nervous system (CNS), patients with RS often show a hypoplastic cerebellum and cerebral calcifications. Some patients may present with ataxia [4].

Affected individuals have a high risk of developing malignant tumors and bone marrow failure. The latter may result in neutropenia, pancytopenia, and aplastic anemia, frequently appearing early in life. Additional features of RS include sparse hair, psychomotor retardation, and intrauterine growth restriction [5] [6].

The diagnosis of Revesz syndrome is reached via a combination of patient history, clinical findings, laboratory results, and genetic testing. It is important that the correct diagnosis of RS be made early, as the risk of developing malignancies, in those affected by the condition, is significant. Moreover, the aforementioned individuals may require and benefit from urgent treatment.

Molecular and genetic studies should be carried out to establish the presence of gene mutations indicative of RS, as well as abnormal telomere lengths [7]. Possible laboratory methods include PCR (polymerase chain reaction), Southern blot, flow cytometry, and fluorescence in situ hybridization (FISH) with immunostaining, [8] [9].

It has been observed that up to half of patients with DC have no observable genetic mutations. The possibility of the syndrome in such patients cannot be ruled out, however, as a diagnosis can be made based on the presence of clinical features consistent with the disease, in addition to molecular studies revealing short telomeres [10].

In older individuals, DC may present with increasingly diverse symptoms that may deviate from the common presentation [11]. The criteria for testing patients for DC or RS may depend on the protocol of a given health facility.
