Musculoskeletal
- Short Humerus
Radiographs showed a short humerus and absent ulna bilaterally. On the upper extremities there was only a single digit. [ashg.org]
Eyes
- Small Eyes
The major developmental defect include hypoplasia of left side of face, ipsilateral ptosis and small eyes, anteverted small nose and philtrum, small ear lobules and rudimentary left thumb while right thumb was absent. [ncbi.nlm.nih.gov]
Skin
- Keratosis
Histopathology of skin biopsy from left upper arm evidenced mild hyper keratosis, focal acanthosis and spongiosis with moderate lymphocytic infiltrate in upper dermis. [ncbi.nlm.nih.gov]

Workup
Method: A comprehensive workup, including an amniocentesis, was performed on a 32-week fetus presenting with massive hydrops and polyhydramnios. [karger.com]

Prognosis
The prognosis in children with 4q-syndrome, depends on the exact chromosomal breakpoint(s) [ 4, 12 ]. In 4q future research, genephenotype correlations are a central focus for global improvement [ 7 ]. [omicsonline.org]
