Mulvihill-Smith syndrome: case report and review

Area of Science:

• Genetics and rare diseases
• Immunology
• Pediatric endocrinology

Background:

• The Mulvihill-Smith syndrome is a rare progeroid disorder.
• Previous reports described limited cases, necessitating further characterization.
• Understanding rare genetic syndromes aids in diagnosis and management.

Observation:

• A 20-year-old male presented with short stature, microcephaly, distinctive facial features, numerous pigmented nevi, hypodontia, immunodeficiency, and a high-pitched voice.
• The patient experienced severe viral infections, allergic conditions, delayed puberty, vision loss, and psychological distress.
• Detailed immunological, facioskeletal, and dental abnormalities were noted.

Findings:

• The patient's condition was confirmed as identical to the Mulvihill-Smith syndrome (McKusick 176690).
• This case expands the known spectrum and clinical progression of this rare disorder.
• The findings challenge previous assumptions of a novel syndrome.

Implications:

• Accurate diagnosis of Mulvihill-Smith syndrome is crucial for appropriate patient care.
• Further research into the genetic basis and pathophysiology of this progeroid disorder is warranted.
• This case highlights the importance of detailed phenotyping in rare disease diagnosis.
