7q11 23 Microduplication Syndrome C1857844
A genetic syndrome caused by duplication of material at chromosome 7q11.23, the reciprocal of Williams syndrome region. This can cause developmental delays, learning challenges, and distinctive facial features. Care involves various specialists providing ongoing support.

Signs and symptoms
Common signs and symptoms that may indicate this condition.
Warning signs - seek immediate care
Congenital heart defects
Structural heart abnormalities including supravalvular aortic stenosis or other vascular issues, though less common than in Williams syndrome.
Seek immediate medical attention if symptoms of heart failure develop such as difficulty breathing, poor feeding, or failure to thrive.
Renal abnormalities
Kidney or urinary tract structural abnormalities including renal artery stenosis or kidney malformations.
If blood in urine, urinary infections, or flank pain occur, seek prompt medical evaluation.
Global developmental delay
(neurologic)Delayed attainment of developmental milestones such as sitting, crawling, walking, and language development compared to typical peers.
Frequency: 80-90% of patients
Speech and language impairment
(neurologic)Significant delays in speech development, with expressive language often more affected than receptive language.
Frequency: 80-90% of patients
Hypotonia
(neurologic)Reduced muscle tone present from infancy, leading to floppiness and delayed motor skills.
Frequency: 75-85% of patients
Motor coordination difficulties
(neurologic)Problems with fine and gross motor skills, including clumsiness, poor balance, and difficulty with tasks requiring precise hand movements.
Frequency: 60-70% of patients
Socially outgoing personality
(behavioral)Extremely friendly and sociable demeanor, similar to Williams syndrome, with strong interest in interacting with others.
Frequency: 60-70% of patients
Characteristic facial features
(constitutional)Subtle facial characteristics including broad forehead, short nose, full cheeks, and full lips, though less distinctive than Williams syndrome.
Frequency: 50-60% of patients
Sound sensitivity
(otologic)Heightened sensitivity to certain sounds (hyperacusis), often finding specific noises uncomfortable or distressing.
Frequency: 40-50% of patients
