Iris hypoplasia with glaucoma

Iris hypoplasia with glaucoma, also known as Iris hypoplasia and glaucoma or simply IHG is a very rare genetic disorder which is characterized by a combination of underdevelopment of the iris and glaucoma. It has been described in three families; two from Russia^[1] and one from London, U.K. It was mapped to a duplication of the q25 region of chromosome 6 through the London family.^[2] Tooth agenesis can sometimes be associated with this disorder.^[3]
