Living with X-linked intellectual disability-cubitus valgus-dysmorphism syndrome

A rare X-linked condition with moderate learning difficulty, elbows that turn outward, a small head, and many moles.

Understanding X-linked intellectual disability-cubitus valgus-dysmorphism syndrome

This X-linked syndrome has moderate intellectual disability, elbows that angle outward (cubitus valgus), and mild small head size.

Other features are a short philtrum (the groove above the lip), deep-set eyes, downslanting eye openings, and multiple moles (nevi). Signs begin in the newborn period or infancy.

Signs & symptoms

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

  • Moderate intellectual disability
  • Elbows that turn outward
  • Small head size (microcephaly)
  • Deep-set eyes
  • Many moles (nevi)
  • Seizures

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