Living with Orofaciodigital syndrome 18

A rare genetic condition with mouth, face, and finger or toe differences and short stature.

Understanding Orofaciodigital syndrome 18

Orofaciodigital syndrome 18 is a rare genetic condition that affects the mouth, face, fingers and toes, and growth.

Features include extra tissue bands in the mouth (frenula), missing front teeth, a square-shaped face with a small forehead, upslanting eyes, and cleft lip. People may have short or extra fingers and toes and short stature. Some have extra neck ribs and differences in the spine bones. GARD lists onset as newborn.
