An X-linked condition with delayed development, little or no speech, and no tears.
Understanding Syndromic X-linked intellectual disability 17
Children have delayed motor and thinking skills, intellectual disability, and absent or very late speech. They also have alacrima, which means no tears. Some have achalasia, a swallowing problem, and uneven pupil sizes. It looks like Triple A syndrome but always includes intellectual disability. Signs may begin in the newborn or infant years.

Symptoms vary from person to person. GARD lists these among the most common:
- Delayed motor and thinking skills

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