The ends of the hand may have "nubbins"—small stumps where the finger would have developed, which may have tiny residual nails.

In most cases, children born with symbrachydactyly are able to adapt to their physical limitations and experience a fully functional life with no treatment. Possible treatment includes
surgery or a routine of regularly stretching the fingers.Symbrachydactyly may be confused with
Poland syndrome , which is a separate disorder which includes a missing pectoral muscle as one of its symptoms.Fact|date=February 2007References
