Iridogoniodysgenesis type 1 - WikiMD's WELLNESSPEDIA

Alternate names[edit]

Iridogoniodysgenesis anomaly, Autosomal dominant; IRID1; IGDA; IGDA syndrome

Definition[edit]

Iridogoniodysgenesis type 1 is a rare condition that affects the eyes. People with this condition are born with malformations of the iris (the colored part of the eye) and cornea, which eventually lead to early-onset glaucoma.

Cause[edit]

Iridogoniodysgenesis type 1 is caused by changes (mutations) in the FOXC1 gene.

Inheritance[edit]

It is inherited in an autosomal dominant manner.

Signs and symptoms[edit]

People with this condition are born with malformations of the iris (the colored part of the eye) and cornea, which eventually lead to early-onset glaucoma.
The irides of affected people are unusually dark.
For example, studies of the condition often describe 'brown' irides as a dark, chocolate color and 'blue' irides as a very dark, slate gray.
The iris also lacks the usual pattern and has a smooth appearance.

Diagnosis[edit]

Treatment[edit]

Management is based on the signs and symptoms present in each person and is generally focused on the screening and eventual treatment of glaucoma.
