Aase syndrome

Last edited: 4/15/2026

Overview

Aase syndrome is characterized by congenital hypoplastic anemia and thumb abnormalities, often accompanied by skeletal anomalies and other developmental features such as joint contractures and cleft palate 123.

Diagnosis

  • Key Diagnostic Criteria: Congenital hypoplastic anemia, thumb anomalies (including triphalangeal thumbs), skeletal abnormalities (clavicles, ilia, distal sacrum, coccyx) 13.
  • Recommended Tests: Radiographic imaging to assess skeletal anomalies 1.
  • Genetic Consideration: Probable autosomal recessive inheritance based on familial cases 3.
  • Management

  • First-Line Treatments: Management of anemia with supportive care and blood transfusions as needed 3.
  • Adjunctive Treatments: Orthopedic interventions for skeletal abnormalities; specific drug classes and doses not detailed in current abstracts 1.
  • Special Populations

  • Pediatrics: Focus on growth failure and developmental milestones; regular orthopedic evaluations 1.
  • Comorbidities: Joint contractures and cleft palate may require multidisciplinary care including orthopedic and craniofacial specialists 2.
  • Key Recommendations

  • Perform radiographic imaging to identify skeletal anomalies characteristic of Aase syndrome (Evidence: Moderate 1).
  • Consider autosomal recessive inheritance in familial cases presenting with Aase syndrome features (Evidence: Expert opinion 3).
  • Provide supportive care for anemia and address skeletal abnormalities with appropriate orthopedic interventions (Evidence: Moderate 13).
