Germline MUTYH mutations and high-grade gliomas: Novel evidence for a potential association.

ABSTRACT: There is growing body of evidence supporting the role of germline mutations in the pathogenesis of pediatric central nervous system (CNS) tumors, and the widespread use of next-generation sequencing (NGS) panels facilitates their detection. Variants of the MUTYH gene are increasingly recognized as suspected germline background of various extraintestinal malignancies, besides their well-characterized role in the polyposis syndrome associated with biallelic mutations. Using a multigene NGS panel (Illumina TruSight Oncology 500), we detected one H3 G34V- and one H3 K27M-mutant pediatric high-grade diffuse glioma, in association with c.1178G>A (p.G393D) and c.916C>T (p.R306C) MUTYH variants, respectively. Both MUTYH mutations were germline, heterozygous and inherited, according to the subseque
