Unusual clinical history of a male infant with Edwards syndrome

Area of Science:

• Medical Genetics
• Developmental Biology
• Clinical Medicine

Background:

• Edwards syndrome (trisomy 18) is a genetic disorder characterized by multiple congenital anomalies.
• Commonly associated malformations include cardiac, renal, and central nervous system defects.

Observation:

• A male infant with Edwards syndrome presented with a unique combination of anomalies.
• Observed features included partial agenesis of the corpus callosum, esophageal atresia with tracheoesophageal fistula, and renal agenesis.

Findings:

• The patient exhibited trisomy 18 with a distinct set of malformations.
• Partial agenesis of the corpus callosum, esophageal atresia with tracheoesophageal fistula, and renal agenesis were not previously reported together in trisomy 18 literature.

Implications:

• This case expands the phenotypic spectrum of Edwards syndrome.
• Further delineation of trisomy 18 is crucial for improved diagnosis and genetic counseling.
