Stuve-Wiedemann syndrome with a novel mutation

Area of Science:

• Medical Genetics
• Pediatric Endocrinology
• Skeletal Biology

Background:

• Skeletal dysplasias are a heterogeneous group of genetic disorders affecting bone and cartilage development.
• Stuve-Wiedemann syndrome is a rare, severe skeletal dysplasia with significant early-life morbidity.
• Consanguinity in parents increases the risk of autosomal recessive genetic disorders.

Observation:

• A term infant presented with intrauterine skeletal dysplasia, short limbs, camptodactyly, and dysphagia.
• The infant experienced respiratory failure, requiring intensive care, and episodes of hyperhidrosis.
• Initial genetic screening was unrevealing, necessitating referral to a specialized network.

Findings:

• The European Skeletal Dysplasia Network facilitated a provisional diagnosis of Stuve-Wiedemann syndrome.
• Genetic testing identified a novel, homozygous mutation in the leukaemia inhibitory factor receptor (LIFR) gene.
• This represents the first reported case of this specific LIFR mutation in the UK.

Implications:

• This case expands the known mutational spectrum of Stuve-Wiedemann syndrome.
• Accurate genetic diagnosis is crucial for understanding prognosis and potential management strategies.
• Specialized networks like the European Skeletal Dysplasia Network are vital for diagnosing rare genetic conditions.
