24973967 Autosomal dominant susceptibility for Paraganglioma is modified by imprinting and mutations in the SDHAF2 gene cause Paragangliomas only when the mutation is inherited from father.
24712571 New mutation found in SDHAF2 gene in pheochromocytoma/paraganglioma patients.
24414418 Data indicate that SDH5 is protected from mitochondrial LON (LONM)-mediated degradation in mitochondria by its stable interaction with SDHA, a state that is dysregulated in hereditary paraganglioma 2 (PGL2).
24322175 Loss of heterozygosity was found in more than 50 % of the von Hippel-Lindau-associated pheochromocytomas, and was correlated with a significant decrease (p < 0.05) in both SDHAF2 and SDHD mRNA expression, which may be suggestive of a pathogenic role.
23983127 Data indicate that succinate dehydrogenase 5 (SDH5) functions as a critical protein in regulating epithelial-mesenchymal transition (EMT) by modulating the glycogen synthase kinase (GSK)-3beta-beta-catenin signaling pathway.
23380393 Studies indicate that the flavinylation factor Sdh5 (SDHAF2) provided insight into the possible mechanism associated with Sdh1 (SDHA) flavinylation.
23291190 Studies indicate that mutations in the mitochondrial complex II structural subunit genes SDHB, SDHC and SDHD and the regulatory subunit gene SDHAF2 in many paraganglioma families.
23174333 Studies indicate that an array of tumor syndromes caused by complex II-associated mutations in genes SDHA, SDHB, SDHC, SDHD, SDHAF1 and SDHAF2 have been identified over a decade.
21224366 We established the SDHAF2 mutation status of PGL2 family members
20972721 Somatic mutations of the SDHAF2 tumor suppressor gene are unlikely to frequently contribute to parathyroid tumor development in sporadic primary hyperparathyroidism.
