A Newborn with Panhypopituitarism and Seizures

Area of Science:

• Genetics
• Pediatrics
• Clinical Medicine

Background:

• Interstitial deletions of the short arm of chromosome 20 (20p) are uncommon genetic events.
• The clinical presentation associated with 20p deletions is not well-established due to limited case reports.

Observation:

• A 4-month-old female presented with a heterozygous deletion at 20p11.21p12.1.
• The patient exhibited panhypopituitarism, cardiac, gastrointestinal, and genitourinary anomalies, alongside distinctive facial features.

Findings:

• This case adds to the sparse literature on 20p interstitial deletions.
• The specific deletion identified (20p11.21p12.1) is associated with a complex phenotype involving hormonal, cardiovascular, digestive, and urogenital systems.

Implications:

• Reporting this rare case helps refine the understanding of 20p deletion phenotypes.
• Further characterization of such deletions is crucial for improved diagnosis and clinical management of affected individuals.
