Transcription factors are frequent cancer driver genes, exhibiting noted specificity based on the precise cell of origin. We demonstrate that ZIC1 exhibits loss-of-function (LOF) somatic events in group 4 (G4) medulloblastoma through recurrent point mutations, subchromosomal deletions and mono-allelic epigenetic repression (60% of G4 medulloblastoma). In contrast, highly similar SHH medulloblastoma exhibits distinct and diametrically opposed gain-of-function mutations and copy number gains (20% of SHH medulloblastoma).

Epidermolysis Bullosa (EB) is a group of genetic skin disorders characterized by extreme skin fragility and blistering. In North African countries, including Tunisia, complex genetic and phenotypic diversity is entangled with a scarcity of scientific research on EB. This lack of knowledge presents a distinct challenge in terms of diagnostic accuracy and patient care.
