Summary

This study describes a boy with features similar to aminopterin embryopathy, even without aminopterin exposure. It highlights the variability and heterogeneity of such developmental conditions.

Area of Science:

  • Medical Genetics
  • Developmental Biology
  • Teratology

Background:

  • Aminopterin embryopathy is a known condition resulting from exposure to the drug aminopterin during pregnancy.
  • Understanding the spectrum of developmental abnormalities is crucial for diagnosis and management.

Observation:

  • A case report details a boy exhibiting multiple congenital anomalies.
  • Manifestations included brachyturricephaly with craniosynostosis, poor cranial mineralization, upslanted palpebral fissures, malar hypoplasia, high-arched palate, micrognathia, abnormal auricles, atrial septal defect (ASD), and minor hand anomalies.
  • The patient also presented with growth and mental retardation.

Findings:

  • The described case shares features with aminopterin embryopathy, termed "Aminopterin Syndrome Sine Aminopterin" (without aminopterin).
  • This adds to the three previously reported convincing cases of this syndrome.
  • The variability and heterogeneity of conditions resembling aminopterin embryopathy are discussed, differentiating from potential Juberg-Hayward syndrome.

Implications:

  • This case expands the understanding of phenotypic variability in congenital anomalies.
  • It underscores the importance of considering genetic and environmental factors in developmental disorders.
  • Further research is needed to elucidate the underlying mechanisms and genetic basis of these heterogeneous conditions.
