Signs and symptoms
Common signs and symptoms that may indicate this condition.
Warning signs - seek immediate care
Seizures
Recurrent seizure activity that may vary in type from focal to generalized seizures.
Seek immediate emergency care for any seizure lasting more than 5 minutes or if it's the first seizure occurrence.
Sensorineural hearing loss
Permanent hearing loss resulting from inner ear or auditory nerve dysfunction, affecting sound perception.
Seek immediate audiological evaluation if hearing loss is suspected or if the infant fails newborn hearing screening follow-up.
Global developmental delay
(neurologic)Delays in reaching developmental milestones such as sitting, walking, and crawling compared to typical children.
Frequency: 80-90% of patients
Speech and language delay
(neurologic)Significant delays in speech development, including late onset of first words and difficulty with language expression and comprehension.
Frequency: 75-85% of patients
Characteristic facial features
(constitutional)Subtle dysmorphic facial features including broad forehead, deep-set eyes, ear abnormalities, and distinctive facial structure.
Frequency: 70-80% of patients
Hypotonia
(neurologic)Reduced muscle tone resulting in floppy limbs and difficulty with motor activities and coordination.
Frequency: 50-60% of patients
Autism spectrum disorder
(neurologic)Social communication difficulties, repetitive behaviors, and challenges with social interaction and engagement.
Frequency: 40-50% of patients
Intellectual disability
(neurologic)Varying degrees of cognitive impairment affecting learning, reasoning, and problem-solving abilities.
Frequency: 45-55% of patients
