Syndrome in question. Costello syndrome

Area of Science:

• Genetics
• Oncology
• Dermatology

Background:

• Costello syndrome (CS) is a rare genetic disorder first described in 1971.
• It is caused by mutations in the HRAS proto-oncogene.
• Clinical manifestations include facial dysmorphism, developmental delays, cardiac and musculoskeletal defects, and an increased risk of malignancies.

Observation:

• This report details a case with a characteristic Costello syndrome phenotype.
• Peculiar skin changes were a notable feature in the observed case.
• The patient presented with features consistent with known CS clinical findings.

Findings:

• The study confirms the association between HRAS mutations and the Costello syndrome phenotype.
• The case underscores the significance of dermatological manifestations in CS diagnosis.
• Increased risk of malignancies and sudden cardiac death are critical concerns in CS patients.

Implications:

• Early recognition of CS, particularly its skin manifestations, is crucial for timely diagnosis and management.
• Understanding the genetic basis (HRAS mutations) aids in risk assessment for malignancies and cardiac issues.
• This case contributes to the broader understanding of Costello syndrome's complex clinical spectrum.
