Involvement in diseasei
Lacrimal duct defect (LCDD)1 Publication
The disease is caused by mutations affecting the gene represented in this entry.
Disease descriptionA condition resulting in the imbalance between tear production and tear drainage. Infants typically manifest persistent epiphora and/or recurrent infections of the lacrimal pathway, such as conjunctivitis. LCDD is caused by failure of the nasolacrimal duct to open into the inferior meatus.
