Inheritance Follows an autosomal dominant pattern. This pattern is associated with a maternal genomic imprinting for SDHD gene
35% of head and neck paragangliomas are inherited.

Clinics

Phenotype and clinics Paragangliomas are highly vascularized tumors derived from neuroectodermal cells. In the familial forms, they are preferentially localized in the head and neck, in the carotid body (80%) and in the glomus jugulare (20%). They may be associated with other neural-crest-derived tumors such as pheochromocytomas. Individuals with familial paragangliomas have a more severe presentation (early age at onset and tumors at multiple sites) than do those with sporadic disease.
Neoplastic risk Tumors are usually benign. Their gravity result of local invasion and important vascularisation. Among 10% of paraganglioma have a malignant evolution.
Treatment Early detection and surgery
Prognosis depends on extent of the disease at the time of diagnosis

Genes involved and Proteins

Gene NameSDHD
Alias SDH4
Location 11q23
DNA/RNA
Description 4 exons
Protein
Description The corresponding protein has 159 amino acids (17 kDa). The 1 to 56 amino acids encode the transit peptide and the 57 to 159 amino acids the mature protein.
Expression wide
Function SDHD encodes a mitochondrial respiratory-chain protein of complex II called "cybS"or small subunit of cytochrome b in succinate-ubiquinone oxidoreductase.
Mutations
Germinal Germ-line mutations in PGL patients are heterozygous and lead to protein truncation (false-sense mutations, insertions and deletions). Missense mutations are also described.
Somatic Loss of wild type allele was usually observed in accordance with the two-hit model for neoplasia.

Gene NameSDHC
Alias SDH3
Location 1q21
DNA/RNA
Description 7 exons
Protein
Description 140 amino acids (15 kDa)
Expression wide
Function SDHC encodes a mitochondrial respiratory-chain protein of complex II called "cybL"or large subunit of cytochrome b in succinate-ubiquinone oxidoreductase. This protein participates with cybS to the anchorage of the complex II in the innner mitochondrial membrane.
Mutations
Germinal Destruction of start codon ATG by a G-to-A transition in exon 1 of SDHC.
Somatic Loss of wild type allele in tumor DNA.

Gene NameSDHB
Alias SDH1
Location 1p36.1-p35
DNA/RNA
Description 8 exons
Protein
Description 252 amino acids (27 kDa)
Expression wide
Function SDHB encodes a mitochondrial respiratory-chain protein of complex II called iron-sulfur protein. This protein participates with the flavoprotein, encoded by SDHA gene, to the enzymatic reaction which proceed to the oxydation of succinate in fumarate coupled with the reduction of ubiquinone to ubiquinol.
Mutations
Germinal Missense mutation leading to protein truncation.
Somatic Not determined.
