We report on a patient carrying a 17q21.31 microdeletion and exhibiting many common syndrome features, together with other clinical signs which have rarely or never been described to date. The detected 695-kb 17q21.31 deletion is larger than in most previously reported cases but is still probably the result of recombination between flanking low-copy repeats. Due to the complexity of the patient's clinical condition, together with the presence of 3 previously unreported symptoms, namely chronic anemia, cervical vertebrae arthrosis and vertebrae fusion, this case is an important addition to the existing knowledge about the 17q21.31 microdeletion syndrome.
