Sometimes: Prader-willi syndrome can be caused by a deletion in chromosome 15 that is visible on routine cytogenetic analysis. Other patents have a submicroscopic deletion that is only visible by fish analysis or cgh microarray. Still others have the syndrome because of uniparental disomy detectable by a methylation study.
