Summary

Progressive infantile encephalopathy, PEHO syndrome, presents with hypotonia and seizures. New cases suggest a PEHO-like syndrome may exist in individuals without typical neuroimaging findings.

Area of Science:

  • Neurology
  • Genetics
  • Pediatrics

Background:

  • PEHO syndrome is a rare, progressive infantile encephalopathy characterized by hypotonia, convulsions, intellectual disability, edema, and optic atrophy.
  • Neuroimaging in PEHO syndrome typically reveals cerebellar and brainstem atrophy.

Observation:

  • A PEHO-like syndrome has been previously described in patients lacking these characteristic neuroimaging findings.
  • This report details four new cases: two isolated individuals and two sisters.

Findings:

  • These four new cases exhibit features consistent with PEHO syndrome but lack the typical neuroimaging abnormalities.
  • The presentation of these cases suggests they may represent a variant or previously unrecognized form of the PEHO-like syndrome.

Implications:

  • These findings expand the phenotypic spectrum of PEHO syndrome and PEHO-like conditions.
  • Further research is needed to elucidate the genetic basis and precise diagnostic criteria for PEHO-like syndromes.
  • Recognizing this variant is crucial for accurate diagnosis and management of affected infants.
