Childhood glaucoma in association with congenital disorder of glycosylation caused by mutations in fucosyltransferase 8.

A rare form of congenital disorder of glycosylation (CDG) was recently discovered in individuals with biallelic mutations in fucosyltransferase 8 (FUT8). The clinical characteristics of patients with FUT8-CDG include intrauterine growth retardation, feeding difficulties, hypotonia, microcephaly, seizures, short stature, developmental delay, and respiratory abnormalities. We report the first case of glaucoma in an infant with FUT8-CGD and hypothesize a pathogenesis for glaucoma.
