I. Arrieta et al., A CASE OF PRADER-WILLI-SYNDROME ASSOCIATED WITH MOSAICISM - CYTOGENETIC AND FISH STUDY, Genes & genetic systems, 71(1), 1996, pp. 31-36
A 15 year-old girl with Prader-Willi syndrome has been studied by cyto
genetic and fluorescence ''in situ'' hibridization analysis, using cen
tromeric probes. These studies have shown that the underlying mechanis
m could be an only copy of chromosome 15 (maternally derived) in some
cells.
