A case of “G 2 Deletion Syndrome” is reported, based on concordant cytogenetic, clinical and dermatoglyphic findings. The definition of the syndrome, as associated with either a ring or a partially deleted chromosome 22, is discussed. The resulting interpretation favours the hypothesis of deletion of the short arm extending into the centromere.
