Adalia Rose’s funeral was held at the Weed Corley Fish Funeral Home in Austin, Texas on 24 January 2022.

What is progeria?

Hutchinson-Gilford progeria syndrome (HGPS) or progeria is also unofficially known as ‘Benjamin Button disease’, after the Brad Pitt film that sees a boy born old before growing younger.

The rare genetic condition affects one in every four million babies and sees them age rapidly because their cells ingest a protein called progerin that is released by an abnormality in their genes.

In Adalia Rose’s case, she was diagnosed with the condition at three months old.

While she made it to the age of 15, most children with HGPS don’t see their 14th birthday.

Symptoms of the disease do not become apparent immediately after birth, but usually begin to occur during the child’s first year.

These include:

  • Slow growth in terms of both height and weight
  • A big head
  • Large eyes, which the kid can’t close properly
  • A small lower jaw
  • Ears that stick out
  • A high-pitched voice
  • Hair loss, including eyelashes and eyebrows

As children with HGPS grow up, they get diseases typical in people aged 50 and over, such as bone loss, hardening of the arteries and heart disease.

Children who have it tend to die of a heart attack or a stroke.

Currently, despite research, there is no cure for the disease.
