Abstract
Prader Willi syndrome is a sporadically seen genetic disease with an incidence of 1:25.000. In 56% of cases there is an interstitial deletion (q11 → q13) on chromosome 15.
Cytogenetic analysis was performed on a four-year-old girl with obesity, mental retardation, recurrent febrile convulsions and a provisional diagnosis of Prader Willi syndrome. High-resolution banding was done to observe the subchromosomal deletion. An interstitial deletion (q11 → q13) on one of the 15th chromosomes was observed in all metaphases.
Keywords: PWS, clinical manifestations, cytogenetic findings, chromosome 15
