Distal arthrogryposis and neonatal hypotonia: an unusual presentation of Prader-Willi syndrome (PWS).

ABSTRACT

The clinical features of Prader-Willi Syndrome (PWS) in the neonate are marked by hypotonia, absence of crying, and feeding difficulties, but the clinical nature of PWS in utero remains unclear. We report a case of PWS with fetal immobility and distal arthrogryposis in a girl admitted the first day of life to the neonatal intensive care unit for severe hypotonia and respiratory distress.
