| Identity |
| Note | other (well known) classes of inherited renal cell carcinomas are: |
| Inheritance | some familly trees resemble autosomal recessive transmission (affected sibs with unaffected parents), other exhibit typical autosomal dominant trasmission with a vertical parent-to-child pattern; the situation is not that of (recessive) tumour suppressor genes as in the retinoblastoma, nor that of a recessive DNA replication/repair gene like in Bloom's, but the overexpression of the mutant allele through (acquired) chromosome imbalance (see below) |
| Clinics |
| Note | no phenotypic sign |
| Neoplastic risk | multiple and/or bilateral papillary renal cell carcinomas, with median age 45 yrs at diagnosis (range 18-79 yrs, most cases being between 35 and 55 yrs old), sex ratio 29M/12F, the presence of asymptomatic cases (mutations have also been detected in tumour-free individuals in these pedigrees pointing to a low expressivity), and still a median age at death of affected individuals at 52 yrs |
| Cytogenetics |
| Note | similar to what is found in sporadic papillary renal cell carcinoma, in particular trisomy 7 and 17 |
| Other findings |
| Note | no loss of heterozygosity at loci on 3p in the tumours; this contrasts with clear-cell renal cell carcinomas which are associated with deletions of 3p |
| Genes involved and Proteins |
| Gene Name | MET |
| Location | 7q31 |
| Protein | |
| Expression | wide |
| Localisation | membrane |
| Function | transmembrane tyrosine kinase receptor for the hepatocyte growth factor/scatter factor (HGF/SF) |
| Mutations | |
| Germinal | found mutated in half of the cases of hereditary papillary renal cell carcinoma so far studied; mutations were in exons 16-19 (tyrosine kinase domain); cases without a detected mutation may either have a mutation in non-tested parts of MET, or mutations in another gene |
| Somatic | the mutant MET allele is duplicated (via the trisomy 7) in the tumours; might lead to a constitutive kinase activation |
