Freya Maclay’s story has touched many people – and tugged on every emotion.

She was born in Hong Kong in August 2022 after her parents, Simone and Ally, had spent three years trying to conceive. Freya was their miracle baby.

But almost a year later, their joy turned to heartbreak when Freya was diagnosed with Tay-Sachs disease, a rare condition in which toxins build up in the brain and spinal cord, leading to seizures, vision and hearing loss, paralysis and eventually death – there is no cure.

Treatment of the disease is focused on reducing its symptoms and improving a patient’s quality of life. Freya’s case is the first in Hong Kong.

Symptoms in babies usually appear at around six months; the life expectancy of an infant with Tay-Sachs is between two and four years. Pneumonia is often the cause of death.
