New MELCAYA Consortium Publication Highlights Diagnostic Challenges in Congenital Nevi and the Value of High-Resolution Sequencing

We are pleased to announce the publication of a new MELCAYA consortium research article , now available in print and indexed in PubMed.

The study, “Copy Number Analysis in Congenital Nevi: Concordance and Diagnostic Limitations of aCGH, sWGS, and Methylation Sequencing,” provides new insights into the diagnostic challenges of atypical nodules arising in congenital nevi. The work highlights important limitations of current diagnostic approaches and demonstrates that higher-resolution sequencing methods may be essential to improve differential diagnosis and support more reliable molecular classification in these complex cases.

As part of MELCAYA Work Package 2 (WP2 – Understanding triggers and transistions from normal melanocytes to nevus to melanoma), this represents the consortium’s first collaborative research paper and marks an important milestone for the project.

The study brings together contributions from Anton Karelin, Ines B. Brecht, Michaela Pogoda, German Demidov, Michael Abele, Dominik T. Schneider, Daniel Aldea, Heather C. Etchevers, Susana Puig, Matthias Hahn, Christopher Schroeder, and Stephan Forchhammer, on behalf of the MELCAYA consortium. It is published in Pigment Cell & Melanoma Research, the official journal of the International Federation of Pigment Cell Societies and the Society for Melanoma Research.
