Medical Eponyms
Nance-Horan syndrome (1974)

Nance-Horan syndrome (NHS [MIM 302350]) was first described independently by researchers in 1974. In Australia by Margaret B. Horan (pediatrician) and Prof Francis (Frank) Alfred Billson (ophthalmologist); and the United States by Walter Elmore Nance et al, as an X-linked syndrome characterized by congenital cataracts, dental anomalies, dysmorphic features, and, in some cases, mental retardation.

A family is described with Hutchinsonian teeth and segmental and posterior sutural cataracts; an hereditary X-linked basis for both anomalies is suggested. The carrier state in this oculodental syndrome is recognisable by the presence of posterior, sutural, punctuate, opacities in the lens and less pronounced dental abnormalities.
