Menkes disease is a rare X-linked recessive disorder of copper metabolism,
characterised by progressive neurological degeneration, abnormal hair and c
onnective tissue manifestations. We report on a girl with classic Menkes di
sease, carrying a de novo balanced translocation 46,X,t(X;13)(q13.3; q14.3)
. The translocation breakpoints at Xq13.3 and 13q14.3 coincide with the Men
kes disease and Wilson disease loci, respectively. (C) 1999 Wiley-Liss, Inc
