SDHAF2 (PGL2-SDH5) and hereditary head and neck paraganglioma.
PURPOSE Hereditary head and neck paraganglioma (HNPGL) syndromes are associated with mutations in the SDHD(PGL1), SDHC(PGL3), and SDHB(PGL4) genes encoding succinate dehydrogenase subunits. We recently described mutations in a previously uncharacterized human gene, now called SDHAF2, and showed that this was the long-sought "imprinted" PGL2 gene. Here, we present a new branch of the Dutch SDHAF...
متن کاملSDH5, a gene required for flavination of succinate dehydrogenase, is mutated in paraganglioma.
Mammalian mitochondria contain about 1100 proteins, nearly 300 of which are uncharacterized. Given the well-established role of mitochondrial defects in human disease, functional characterization of these proteins may shed new light on disease mechanisms. Starting with yeast as a model system, we investigated an uncharacterized but highly conserved mitochondrial protein (named here Sdh5). Both ...
متن کاملFamilial malignant retroperitoneal paraganglioma.
Paragangliomas are neuroendocrine tumours and those occurring in the head and neck have well recognized familial association. Retroperitoneal paragangliomas are uncommon and we present two cases of familial malignant retroperitoneal paraganglioma. Review of the literature revealed marked differences in the incidence and malignant potential of familial and non-familial paraganglioma. In contrast...
متن کاملFamilial paraganglioma of head and neck
Paragangliomas are tumors originated from non-chromaffin paranganglia cells derived from the neural crest. These highly vascular tumors are located in the region which extends from skull base to arcus aorta. Head and neck paragangliomas have rare occurence constituting 0.012% of all the body tumors and 0.6% of head and neck tumors. Head and neck paragangliomas occur in sporadic and familial for...
متن کاملModeling dioxygenase enzyme kinetics in familial paraganglioma
Hypoxia inducible factors (HIFs) play vital roles in cellular maintenance of oxygen homeostasis. These transcription factors are responsible for the expression of genes involved in angiogenesis, metabolism, and cell proliferation. Here, we generate a detailed mathematical model for the enzyme kinetics of α-ketoglutarate-dependent HIF prolyl 4-hydroxylase domain (PHD) dioxygenases to simulate ou...
