Background: Web-based information and social support are commonly used in rare disease communities where geographic dispersion and limited provider expertise complicate in-person support. We examined web-based resource use among caregivers of individuals with telomere biology disorders (TBDs), which are rare genetic conditions with long diagnostic odysseys and uncertain prognoses including multiorgan system cancer risk.
Objective: This study explored internet-based information-seeking and social support practices and perspectives of patients with TBDs and their caregivers.

Introduction And Importance: Dyskeratosis congenita (DC) is a rare multisystem disorder primarily characterized by bone marrow failure due to telomere shortening. Typical clinical features include oral leukoplakia, skin hyperpigmentation, and nail dystrophy, along with an increased risk of malignancies. Hoyeraal-Hreidarsson syndrome (HH), a severe variant of DC, is associated with profound neurological and immunological complications, emphasizing the importance of early diagnosis and genetic evaluation to guide appropriate management.

Telomeres protect the ends of chromosomes but shorten following cell division in the absence of telomerase activity. When telomeres become critically short or damaged, a DNA damage response is activated. Telomeres then become dysfunctional and trigger cellular senescence or death.

Background: Medical uncertainty may cause distress and challenge medical decision-making for patients with rare diseases and their caregivers. Few studies have examined the experience and management of medical uncertainty in rare disease and the dynamics of multiple medical uncertainty sources, issues, and management strategies.
Objective: We explored the experience and management of uncertainty in individuals with telomere biology disorders (TBDs), a set of rare cancer-prone bone marrow failure syndromes, and their caregivers.
