Summary
Prader-Willi syndrome can manifest in newborns with hypotonia and feeding issues. Early consideration in neonates with these symptoms aids timely diagnosis and intervention.
Area of Science:
- Pediatrics
- Genetics
- Neonatology
Background:
- Prader-Willi syndrome (PWS) is a complex genetic disorder.
- Classic PWS features like obesity and hypogonadism are typically recognized later in childhood.
- Neonatal presentation often includes severe hypotonia and feeding difficulties.
Observation:
- This case details an infant with neonatal hypotonia, feeding problems, failure to thrive, developmental delay, pale skin, edema, cryptorchidism, and micrognathia.
- The infant's initial symptoms suggested PWS, prompting molecular testing.
- Diagnosis of PWS was confirmed via molecular testing at five months of age.
Findings:
- The study confirms that key PWS features can be present from the neonatal period.
- Molecular testing is crucial for definitive diagnosis in infants with suggestive symptoms.
- Early identification allows for prompt management of PWS.
Implications:
- Neonatologists and pediatricians should consider PWS in infants presenting with severe hypotonia and feeding challenges.
- Early diagnosis of PWS enables timely intervention, potentially improving long-term outcomes.
- Recognizing neonatal signs of PWS is vital for prompt genetic evaluation.
