🧬 Excited to share that our paper “Expanding the phenotypic spectrum associated with ZIC1 variants: a neurodevelopmental disorder with and without craniosynostosis” has been published in Genetics in Medicine!
This international collaborative study identified 30 individuals from 22 families carrying heterozygous ZIC1 variants, helping to refine the genotype–phenotype correlation.
🔬 Our findings show that:
• Variants in the last exon are associated with craniosynostosis and brain abnormalities (likely gain-of-function).
• Variants in earlier exons disrupt the zinc finger domain and are linked to neurodevelopmental disorders without craniosynostosis (loss-of-function).
👏 Congratulations to Aida Bertoli Avella for this excellent work and to all collaborators involved.
📄 The poster is now available in Genetics in Medicine.
