Prolidase deficiency, a rare enzyme disorder affecting proline metabolism, typically presents with skin issues, infections, and developmental delays. This case report highlights pathologic myopia as a newly identified clinical feature of this condition.

Area of Science:

  • Biochemistry
  • Genetics
  • Metabolic Disorders

Background:

  • Prolidase deficiency is an extremely rare autosomal recessive metabolic disorder.
  • It results from mutations in the proline dipeptidase (PEPD) gene, leading to impaired proline metabolism.
  • This impairment affects collagen turnover and the metabolism of other proline-rich proteins.

Observation:

  • A 25-year-old patient presented with the classic features of prolidase deficiency.
  • These features included skin lesions, recurrent infections, characteristic facial features, mental retardation, and splenomegaly.
  • The patient also exhibited pathologic myopia, a previously undescribed association.

Findings:

  • The study details a case of prolidase deficiency in a 25-year-old individual.

  • The patient displayed the full spectrum of previously recognized clinical manifestations.
  • Pathologic myopia was identified as a novel clinical finding in this patient.

    • Implications:

    • This case expands the known clinical spectrum of prolidase deficiency.
    • The inclusion of pathologic myopia may aid in earlier diagnosis and management.
    • Further research into the proline-metabolism pathway's role in ocular health is warranted.
