Hypothesis

What are the phenotypic effects of a de novo analphoid supernumerary marker chromosome in a child?

Conclusion

This case adds to the limited number of reported cases of analphoid inversion-duplication 3q supernumerary marker chromosomes and highlights the importance of precise genetic diagnosis.

Supporting Evidence

  • The child presented with several dysmorphic features.
  • The marker chromosome was characterized as analphoid inversion-duplication 3q25.33-qter.
  • This case adds to the eight previously reported cases of analphoid inversion-duplication 3q supernumerary marker chromosomes.

Takeaway

A baby girl had a special chromosome that caused her to have some unusual physical features. This study helps doctors understand more about such rare chromosomes.

Methodology

The study involved cytogenetic analysis using G-banding, FISH, and aCGH on skin fibroblast cells.

Limitations

The study is based on a single case, limiting the generalizability of the findings.

Participant Demographics

One month old female child, second child of unrelated parents.
