Living with Frontonasal dysplasia-bifid nose-upper limb anomalies syndrome

A rare syndrome with distinct facial and nose differences, plus hand and arm differences, from newborn age.

Understanding Frontonasal dysplasia-bifid nose-upper limb anomalies syndrome

Frontonasal dysplasia-bifid nose-upper limb anomalies syndrome is a rare form of frontonasal dysplasia with facial features and limb differences.

Features include wide-set eyes, almond-shaped eyes, a nose that is split or has an absent tip, and downturned corners of the mouth. Limb differences such as Poland anomaly, bent fingers, fewer fingers or fused fingers can occur. Others reported include an encephalocele, a blocked rear nasal passage, and kidney, heart or brain differences.

Signs & symptoms

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

  • Wide-set eyes
  • Nose with a split or missing tip
  • Wide nasal bridge
  • Hand and arm differences
  • Curved little fingers (clinodactyly)
  • Facial asymmetry

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