The mean age at diagnosis of phaeochromocytoma in VHL disease is ~20 years compared with 43.9 years in sporadic cases, reflecting both increased detection through surveillance (see below) and a predisposition to early onset tumours (Maher et al. 1990, Neumann et al. 2002). Phaeochromocytoma in VHL disease is usually intra-adrenal but ~10% are extra-adrenal (Neumann et al. 1993, Walther et al. 1999). Many VHL phaeochromocytomas are asymptomatic at diagnosis and while this is, in part, related to the early diagnosis by routine screening the number of asymptomatic tumours is higher than in other familial disorders such as multiple endocrine neoplasia Type 2 (MEN2). Compared with MEN2, VHL phaeochromocytomas are relatively less likely to express the enzyme phenylethanolamine-N-methyltransferase (PNMT) that converts noradrenaline to adrenaline such that they almost exclusively produce nor-adrenaline. However, in MEN2 there is a relative excess of adrenaline that causes the characteristic clinical manifestations such as tachycardia and episodes of tremulousness (Eisenhofer et al. 2001).
The most frequent pancreatic manifestation of VHL disease is benign serous cysts that occur in up to 90% of VHL patients and rarely cause clinical disease (Neumann et al. 1991, Hough et al. 1994, Hammel 2000). Benign microcystic adenomas also occur in a minority of cases (~12%) (Hammel et al. 2000). More significantly, 510% of VHL patients develop pancreatic tumours, most commonly non-secretory islet cell tumours (also known as neuro-endocrine tumours (NET)) which may be multifocal in 50% of affected individuals (Lubensky et al. 1998, Libutti et al. 1998, 2000, Marcos et al. 2002). These tumours are often asymptomatic and are usually detected incidentally during routine abdominal surveillance of VHL patients (Hough et al. 1994, Libutti et al. 1998, Hammel et al. 2000). The mean age at diagnosis of pancreatic NETs in VHL patients is younger than in sporadic cases (35 vs 58 years) (Lubensky et al. 1998). This earlier diagnosis may also contribute to the better prognosis of VHL-associated compared with sporadic NETs. Most VHL NETs are less than 3 cm and are slow growing. Although fewer than 10% metastasise, larger lesions may be more sinister and Marcos et al. (2002) found that ~20% of lesions >3.0 cm in diameter had metastasised to the liver.

The phenotypic variability that is characteristic of VHL disease may reflect mosaicism or modifier effects, but allelic heterogeneity is the major cause (Crossey et al. 1994, Webster et al. 1998, Sgambati et al. 2000). Thus, there are complex genotypephenotype correlations in VHL disease particularly with regard to the presence or absence of phaeochromocytoma. VHL disease has been divided into Type 1 kindreds (in which affected individuals may have retinal or CNS haemangioblastomas and RCC but not phaeochromocytoma) and Type 2 kindreds (at least one affected individual has phaeochromocytoma). Type 2 kindreds are further subdivided into Type 2A (in which retinal and CNS haemangioblastomas but rarely RCC occur) and Type 2B (haemangioblastomas, RCC and phaeochromocytoma occur) (Crossey et al. 1994, Brauch et al. 1995, Maher et al. 1996, Zbar et al. 1996). Subsequently, a subset of families with isolated familial phaeochromocytoma were shown to have germline VHL gene missense mutations (Type 2C VHL disease) (Crossey et al. 1995, Neumann et al. 1995, Woodward et al. 1997). Whilst in some cases this reflected variable expression (e.g. p.R167w mutations that are usually associated with a Type 2B phenotype were found), in other families the mutation had not been described in other subtypes and appeared to be associated with a phaeochromocytoma only phenotype. Most patients with Type 2 VHL disease have missense mutations whereas in Type 1 families large deletions and truncating mutations predominate (Crossey et al. 1994, Maher et al. 1996, Zbar et al. 1996). Thus, it appeared that complete loss of function mutations were associated with a low risk of phaeochromocytoma, implying that Type 2 missense mutations may retain some functional activity. Consistent with this hypothesis, it was subsequently demonstrated that many missense mutations causing a Type 1 phenotype involved core hydrophobic residues and were predicted to disrupt protein structure, whereas Type 2 phenotype missense mutations involved substitutions at a surface amino acid that does not cause a total loss of function (Stebbins et al. 1999). Although no specific genotypephenotype correlations have been defined for pancreatic NETs occurring in VHL disease, it has been observed that they may be more frequently associated with phaeochromocytoma (Binkovitz et al. 1990, Marcos et al. 2002). Thus Marcos et al. (2002) reported that up to 40% of VHL patients with a pancreatic NET had a surgically confirmed adrenal phaeochromocytoma. Such an association may reflect their shared embryonic neural crest origins and common mechanisms of tumourigenesis.

VHL-related tumours are highly vascular and demonstrate over-production of hypoxia-inducible mRNAs such as vascular endothelial growth factor (VEGF) (Wizigmann-Voos et al. 1995). Many hypoxia-inducible mRNAs are under the control of heterodimeric transcription factors (HIF-1 and HIF-2), which consist of a degradable alpha subunit and a stable constitutively expressed beta subunit (Schofield & Ratcliffe 2004). Under normoxic conditions, HIF-1
and HIF-2
are rapidly polyubiquitylated and destroyed by the proteosome, but under hypoxic conditions the alpha subunits are stabilised and HIF-1 and HIF-2 activate transcription of a wide repertoire of hypoxia-inducible mRNAs (Schofield & Ratcliffe 2004 and references within).
The crucial link between pVHL and the regulation of hypoxia-inducible mRNAs was provided by Maxwell and colleagues who showed that pVHL interacts with the regulatory alpha subunit of HIF and targets it for oxygen-dependent polyubiquitylation and proteosomal degradation (Maxwell et al. 1999, Cockman et al. 2000). pVHL mutants failed to degrade the alpha subunits leading to stabilisation of HIF-1 and HIF-2 and inappropriate expression of hypoxia-inducible mRNAs (see Fig. 1
). The oxygen-dependent interaction of pVHL with HIF-
is provided by the hydroxylation status of key HIF-
proline residues (Pro-402 and Pro-564) (Ivan et al. 2001, Jaakkola et al. 2001, Masson et al. 2001, Yu et al. 2001). Thus, in the presence of oxygen, HIF-
subunits are hydroxylated at the conserved prolyl residues by members of the egg laying defective nine (EGLN) family (also known as the PHD family) (Bruick & McKnight 2001, Epstein et al. 2001). Molecular oxygen and 2-oxoglutarate are essential cosubstrates and iron is an essential cofactor (Epstein et al. 2001, Schofield & Ratcliffe 2004) and, in the absence of these, hydroxylation does not occur and pVHL is unable to bind the alpha subunits. In humans, three EGLN homologues have been implicated in HIF-
modification (PHD1/EglN2/HIFPH1, PHD2/EglN1/HIFPH2 and PHD3/EglN3/HIFPH3) (Bruick & McKnight 2001, Epstein et al. 2001).

The precise role of HIF dysregulation in the pathogenesis of VHL-related phaeochromocytomas is unclear. Thus both Type 2A and Type 2B VHL mutations (associated with a high risk of phaeochromocytoma) are unable to regulate HIF (Clifford et al. 2001) and comparison of gene expression patterns in VHL and MEN2 phaeochromocytomas revealed that many of the genes over-expressed in VHL compared with MEN2 tumours were linked to the hypoxia-driven angiogenic pathways (e.g. VEGF, placental growth factor, angiopoietin 2, tie-1, VEGF receptor 2 and neuropilin-1) (Eisenhofer et al. 2004). Phaeochromocytomas from SDHB and SDHD gene carriers demonstrate evidence of HIF activation and over-expression of hypoxia-inducible genes (Gimenez-Roqueplo et al. 2001, Pollard et al. 2005) and SDH inactivation has been shown in vitro to inhibit HIF-
prolyl hydroxylases leading to stabilisation and activation of HIF-1
, further implicating HIF dysregulation in phaeochromocytoma tumourigenesis (Selak et al. 2005). Furthermore, comparison of gene expression profiles in VHL-, SDHB- and SDHD-associated phaeochromocytomas demonstrated a shared transcription profile of reduced oxidoreductase and increased angiogenesis/hypoxia target genes (Dahia et al. 2005). However, the role of HIF-1 and HIF-2 in phaeochromocytoma tumourigenesis may be complex because Type 1 VHL mutations (with a low risk of phaeochromocytoma) are also unable to regulate HIF, and Type 2C (phaeochromocytoma only) pVHL mutants retain the ability to regulate HIF-
subunit degradation, suggesting that HIF dysregulation is not essential for the development of phaeochromocytomas in VHL disease (Clifford et al. 2001, Hoffman et al. 2001). Hence, it was suggested that the complex genotypephenotype relationships observed in VHL disease were consistent with multiple and tissue-specific functions.
Recently, Lee et al. (2005) have suggested a novel HIF-independent pVHL function that links phaeochromocytoma in VHL disease to that in other familial phaeochromocytoma predisposition syndromes. Thus, they hypothesised that inherited phaeochromocytomas originate from sympathetic neuronal precursor cells that usually undergo c-Jun dependent apoptosis during embryogenesis when growth factors such as nerve growth factor (NGF) become limiting (Estus et al. 1994, Schlingensiepen et al. 1994, Ham et al. 1995, Xia et al. 1995) (see Fig. 2
). JunB is an antagonist of c-Jun such that increased levels of JunB attenuate c-Jun induced apoptosis in phaeochromocytoma cells with NGF withdrawal. Pathogenic NF1 and RET mutations are known to enhance signalling by NGF receptors and hence promote neuronal survival (Vogel et al. 1995, Dechant 2002). Lee et al. (2005) found that all pVHL mutants tested (including 2C mutants that retain the ability to degrade HIF) failed to down-regulate JunB following NGF withdrawal, thus promoting cell survival (the pVHL effect on JunB is mediated, in part, through an HIF-independent, atypical protein kinase C pathway). Furthermore, a similar effect was also demonstrated with activating mutations of RET. EglN3 (PHD3) (a member of the proline hydroxylase EGLN family) had previously been shown to be induced in sympathetic neurons following NGF withdrawl and to provoke apoptosis when over-expressed in phaeochromocytoma cells (Lipscomb et al. 1999, 2001, Straub et al. 2003) and Lee et al. (2005) reported (a) that EglN3, but not EglN1, acts downstream of c-Jun and is both necessary and sufficient to induce neuronal apoptosis following NGF withdrawal and (b) that EglN3 is sensitive to changes in SDH activity such that after SDH inactivation, succinate accumulation inhibits the activity of EglN3 thus preventing apoptosis of the neuronal precursor cells. Although SDH is a mitochondrial enzyme, the succinate that accumulates is transported to the cytosol by the dicarboxylate carrier located on the inner mitochondrial membrane. Thus, these findings provide a common link between phaeochromocytoma development in inherited phaeochromocytoma susceptibility syndromes as (a) NF1 inhibits downstream signalling by the NGF receptor, TrkA, and loss of NF1 promotes NGF independent survival of embryonic peripheral neurons (Vogel et al. 1995) and (b) activation of RET, like loss of pVHL, has been shown to lead to the induction of JunB and thus attenuates apoptosis after NGF withdrawal. In addition, the concept that germline NF1, RET, SDH subunit and VHL mutations promote phaeochromocytoma development by allowing sympathetic neuronal progenitors to escape from developmental apoptosis is consistent with the observation that somatic inactivation of these genes is infrequent in sporadic phaeochromocytoma (whereas somatic VHL inactivation occurs in most sporadic clear cell RCC) (Maher & Eng 2002). It should be noted that whereas all pVHL mutants fail to down-regulate JunB (including Type 1 mutants which are not associated with phaeochromocytoma), pVHL has multiple effects on EglN3, and Type 1 and Type 2 pVHL mutants differ with respect to their effect on EglN3/PHD3 expression (increased in Type 1 mutants). Thus, Type 1 mutations increase EglN3 expression whereas Type 2 mutations result in reduced EglN3 expression.
