Scientists hunt for genes behind rare eye conditions

NCT ID NCT01778543

First seen Jun 24, 2026 · Last updated Jun 27, 2026 · Updated 2 times

Summary

This study aims to uncover the genetic causes of a group of eye conditions called MAC (microphthalmia, anophthalmia, and uveal coloboma), which can lead to vision loss or blindness. Researchers will collect DNA samples from 600 people—both those with MAC and their close relatives—to search for gene changes linked to these disorders. Participants will undergo eye exams and provide blood or saliva samples. The goal is to better understand why these conditions occur, which may help with future diagnosis and family planning.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

What this could lead to

If successful, this research could identify new genes linked to MAC, improving genetic counseling and future diagnostic approaches.

What could go wrong

This is an observational study, not a treatment trial. It may not directly benefit participants, and genetic findings may take years to translate into clinical use.
