Understand MCT8 Deficiency

Knowledge can help families find answers, connect with appropriate specialists and better understand what the future may hold.

MCT8 deficiency is a rare genetic condition that affects the way thyroid hormones are transported into cells throughout the body.

Thyroid hormones play a critical role in growth and development. In people with MCT8 deficiency, these hormones cannot effectively enter certain cells, particularly within the central nervous system.

Advancing Understanding and Care

MCT8 deficiency affects more than an individual’s physical health. It can shape daily life for the entire family, requiring ongoing medical care, therapy and coordination between multiple healthcare professionals.

Understanding these wider challenges is essential to supporting patients, parents and caregivers.

Researchers and healthcare professionals continue to build understanding of MCT8 deficiency, including its underlying biology, progression and long-term impact.

Egetis works alongside medical experts and the wider MCT8 deficiency community to connect scientific evidence with lived experience and contribute to better-informed care.

While treatment approaches may vary, care is typically focused on addressing the complex effects of MCT8 deficiency and supporting the long-term health and well-being of patients.

Current approaches aim to:

• Support thyroid hormone activity in tissues where it is reduced
• Reduce the effects of excess thyroid hormone activity in peripheral tissues
• Address key contributors to disease burden and long-term complications

Treatment and care decisions should always be discussed with a qualified healthcare professional.
