Parents will move mountains to find cures for their children

A rare disease diagnosis is heartbreaking, but getting a diagnosis is also an empowering milestone. Knowing the enemy is the first step in defeating it, and knowing the science behind a condition is the first step in getting to treatment.

The Association for Creatine Deficiencies (ACD) is a small yet growing parent-led advocacy organization that provides patient, family, and public education to advocate for early diagnosis of cerebral creatine deficiency syndromes (CCDS) and to promote and find medical research for treatments and cures. ACD leaders know they can’t afford to be bystanders in the research process waiting on developments from the medical field. As such, the organization is committed to being an active player in research and fostering a symbiotic collaboration where researchers and parents work together. With three rare diseases under one umbrella, the ACD is leveraging the power of a stronger, united community to drive research.

Guanidinoacetate methyltransferase deficiency (GAMT) and L-Arginine:glycine amidinotransferase (AGAT) deficiencies are treatable, but many states still don’t screen for them at birth. Creatine transporter deficiency (CTD) is currently untreatable. Common clinical symptoms include severely impacted speech, language and motor skills; intellectual disability; behavioral problems; hypotonia (weak muscle tone); and, in many cases, seizures. CCDS are severely under-diagnosed due to lack of awareness and availability of clinical diagnostic tests.

ACD’s goal is to identify effective treatments for all three CCDS, ultimately ensuring that children with a creatine deficiency are diagnosed at birth and receive prompt treatment. To reach this goal, ACD aims to get clinical trials underway soon and centralize patient data in an open science patient registry. With small patient populations, this knowledge and access are critical for considering meaningful treatment outcomes.

Research Progress & Capacity Building Updates

Since joining the Rare As One network, ACD has made significant capacity-building and research progress. Highlights include:

  • A growing board of directors and staff
  • Formation of a gene therapy consortium
  • Expanding the CCDS research network by funding a fellowship program for early-career researchers
  • Two virtual research-focused conferences with over 200 attendees
  • GAMT, one of the three CCDS, is one step closer to universal newborn screening, following coordinated efforts led by ACD
  • Building and launching the CreatineInfo patient registry and natural history study
  • Work towards expanding the CCDS treatment research pipeline with early stage research efforts
  • Knowing the enemy is the first step in defeating it, and knowing the science behind a condition is the first step in getting to treatment.
