18q syndrome is a rare chromosomal anomaly where there is a deletion of part of the long arm of chromosome 18. Associated symptoms and findings vary widely, as does their severity. Characteristic features include short stature, mental retardation and hypotonia, facial and distal skeletal abnormalities. Chromosome 18q syndrome appears to result from a spontaneous, sporadic chromosomal error during very early embryonic development.
