Area of Science:

  • Genetics
  • Skeletal Dysplasias
  • Developmental Biology

Background:

  • Partial monosomy 21 is a rare chromosomal abnormality.
  • Understanding the phenotypic spectrum of chromosomal abnormalities is crucial for diagnosis and management.
  • Skeletal anomalies are common in genetic disorders.

Observation:

  • A newborn presented with clinical features suggestive of a genetic disorder.
  • A skeletal survey was performed as part of the diagnostic workup.
  • Strikingly abnormal clavicles were noted on the skeletal survey.

Findings:

  • The newborn was diagnosed with partial monosomy 21.
  • The clavicular abnormalities represent a significant and unusual feature of this case.
  • This case expands the known skeletal manifestations associated with partial monosomy 21.

Implications:

  • Highlights the importance of detailed skeletal examination in diagnosing genetic syndromes.
  • Suggests that clavicular morphology can be a key indicator in partial monosomy 21.
  • Informs genetic counseling and clinical management for families affected by chromosome 21 abnormalities.
