Living with Familial median cleft of the upper and lower lips

A rare condition present from birth with a cleft in the middle of both the upper and lower lips and some tooth and gum differences.

Understanding Familial median cleft of the upper and lower lips

Familial median cleft of the upper and lower lips is a rare condition present from birth in which both lips have a cleft in the middle.

The lower lip cleft involves only the colored edge of the lip, and the upper lip cleft involves muscle. People may also have a double lip frenulum, fused gum and lip tissue, poorly aligned teeth, and a gap between the front teeth. Features can vary within a family.

Signs & symptoms

Symptoms vary from person to person. GARD lists these among the most common:

  • Cleft in the middle of the upper lip
  • Cleft lower lip
  • Fusion of the gums
  • Gap between the teeth (diastema)
  • Irregular teeth
  • Differences in the jaw or midface

Not everyone has every symptom. GARD's list comes from the Human Phenotype Ontology.
