Be Part of the Solution
Every family that shares data brings ZTTK closer to that threshold. Your participation does not require travel, procedures, or significant time — and it directly powers the research that could lead to treatments.
Three Steps to Get Involved
Join the Contact Registry
~2 minutesRegister with the ZTTK SON-Shine Foundation so we can count you or your SON-Shine, share research updates, and connect you with relevant study opportunities as they arise.
Join the Registry →Share Your Health Records
~5 minutes to enrollThrough our partnership with Citizen Health, US-based families can securely share de-identified medical records with researchers. Citizen retrieves your data directly from healthcare providers — a one-time setup that continuously feeds the research pipeline.
Enroll with Citizen Health →Complete Patient Surveys
~20 minutes initiallyThe Rare-X data collection program gathers patient-reported outcomes through structured surveys available in English, French, Spanish, and Portuguese. Start with the head-to-toe assessment, then complete follow-up surveys on specific symptoms over time.

Tracking the Full Picture
Natural history studies track how a disease presents and progresses over time through questionnaires and medical record reviews — the evidence base regulators, researchers, and pharmaceutical companies require before investing in treatment development.
Designing Better Trials
Your data helps researchers understand how ZTTK changes over a lifetime, design clinical trials with meaningful endpoints, reduce the need for placebo arms in pediatric trials, and demonstrate that the ZTTK population is large and well-characterized enough to justify therapeutic investment.
A Return for Your Contribution
If any data you contribute is used in research conducted by pharmaceutical companies developing treatments, Rare-X participants may receive a share of licensing fees through their data monetization model.
