Understanding X-linked intellectual disability, Stocco dos Santos type

X-linked intellectual disability, Stocco dos Santos type, is a genetic condition present from birth that affects thinking and the eyes.

Some babies are born with a partly dislocated hip. People can have delayed speech, severe intellectual disability, a low nasal bridge, extra body hair, hyperactivity, a rounded upper back, and repeated respiratory infections. Females typically have milder symptoms, and some have none.

Signs & symptoms

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

  • Severe intellectual disability
  • Delayed speech and language

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