Living with Trisomy 4p
A rare chromosome condition with an extra piece of chromosome 4 that can slow growth and development.
Understanding Trisomy 4p
It varies a lot between people. It typically includes slow growth before and after birth, developmental delay, and distinctive facial features. Bone, kidney, heart, and eye differences can also occur, and boys may have genital differences. It is noticed during pregnancy, at birth, or in infancy.
Signs & symptoms
Symptoms vary from person to person. GARD lists these among the most common:
- Delayed development and cognitive impairment
- Small head (microcephaly)
- Low muscle tone (hypotonia)
- Large ears and a round face
- Crossed eyes (strabismus)
- Scoliosis and short neck
Not everyone has every symptom. GARD's list comes from the Human Phenotype Ontology.
