When her daughter died, Aldrich was living in Fairfax, Virginia, in the United States.
She is now a second-year biomedicine student at the University of Otago.
Since Claire’s death, Aldrich has had twins and now has three healthy young children.
Yesterday, she joined about 20 rare disease researchers at the university to mark Rare Disease Day, the last day of February, and the lead-in to Rare Disease Month this month.
Otago University Brain Health Research Centre director Professor Stephanie Hughes said she often heard it was lonely for parents of children with rare diseases.
The disease she works on is a rare, childhood neurological disorder called Batten disease. There are only a couple of patients in New Zealand.
However, work was under way, by a group of about 20 university researchers, to establish a “rare diseases network”, which could help to end the isolation.
“The aim is to try and link in clinicians with translational research and basic research so that we are getting an idea of why we are doing what we do and we have a more direct line of sight to what’s important for the family,” Hughes said.
Rare diseases could present a raft of different symptoms.
However, most commonly they were genetic in origin, about 50 per cent affected children, and about 95 per cent had no treatments, she said.
To commemorate Rare Disease Day, last night the university clocktower, Tūhura Otago Museum, Otago Boys’ High School and the Dunedin Railway Station were lit in orange.
