Key Points

Atypical deletions within the 15q11.2 region indicate significant genetic variability in prader-willi syndrome cases, which complicates diagnosis.
Recent reports document two cases highlighting the need for careful case interpretation and symptom-based management strategies.
Genetic analysis underscores the complexity of the prader-willi syndrome locus and its influence on clinical presentation and outcomes.
Calls for further controlled experimental research aim to clarify the regulatory landscape surrounding the prader-willi syndrome locus and its deletions.

Implication

Observational analysis reveals genetic complexity in prader-willi syndrome cases with atypical deletions, suggesting cautious interpretation.

Abstract

This letter discusses two recent reports of Prader–Willi syndrome (PWS) cases with atypical deletions within the 15q11.2 region. The genetic and clinical complexity highlights the need for caution when interpreting individual cases, supports a symptom‐based management approach, and calls for controlled experimental research to elucidate the regulatory landscape of the PWS locus.
