Since the characteristic mesomelic limb abnormalities of the autosomal
-dominant Nievergelt syndrome (NS) may be casually nonspecific, we are
unsure whether our patient with these abnormalities but also with sev
ere, symmetrical hand and foot anomalies has an unusual form of Niever
gelt syndrome or a previously apparently undescribed syndrome, This in
fant's condition could represent an autosomal-dominant new mutation, o
r an autosomal or X-linked recessive disorder. (C) 1997 Wiley-Liss, In
