This syndrome is characterised principally by Sprengel anomaly (upward displacement of the scapula) and hydrocephaly. Other anomalies such as psychomotor retardation, psychosis, brachydactyly, and costovertebral dysplasia may also be present.

Digits that appear disproportionately short compared to the hand/foot. The word brachydactyly is used here to describe a series distinct patterns of shortened digits (brachydactyly types A-E). This is the sense used here.
