Schinzel-Giedion syndrome

Area of Science:

• Pediatric Medicine
• Medical Genetics
• Surgical Urology

Background:

• Schinzel-Giedion syndrome (SGS) is a rare genetic disorder characterized by distinctive facial features, developmental delay, and increased risk of certain cancers.
• Urinary tract abnormalities, including hydronephrosis, are common complications in infants diagnosed with SGS, necessitating early detection and management.
• Previous sibling mortality due to Trisomy 18 in this family underscores the importance of genetic counseling and accurate diagnosis in subsequent pregnancies.

Observation:

• A 2-month-old female infant presented with poor feeding, midfacial hypoplasia, coarse dysmorphic features, choanal stenosis, abdominal distention, and bilateral talipes equinovarus.
• Imaging revealed severe left and moderate right hydronephrosis, indicating significant urinary tract obstruction.
• The infant's clinical presentation and family history were suggestive of a genetic syndrome.

Findings:

• The infant was diagnosed with Schinzel-Giedion syndrome based on characteristic clinical features.
• Surgical intervention, specifically a left ureteroneocystostomy with tailoring, was performed at 3 months of age.
• The procedure aimed to correct the ureteropelvic junction obstruction, preserve renal function, and prevent recurrent urinary tract infections.

Implications:

• This case emphasizes the critical role of prompt diagnosis and multidisciplinary management in infants with Schinzel-Giedion syndrome to address congenital anomalies.
• Early surgical correction of hydronephrosis is crucial for preserving kidney function and improving long-term outcomes in affected children.
• Understanding the spectrum of SGS manifestations aids in genetic counseling and family planning for affected families.
