Genes implicated inPTEN   SDHB   SDHD  
Inheritance autosomal dominant; high penetrance (close to 100% by the age of 30 yrs); highly variable expressivity (between and within families)


Phenotype and clinics clinical manifestations usually occur during the 2nd and 3rd decade; they are dystrophic, hamartomatous or tumoral lesions including the following to variable extend:
- mucocutaneous papillomatous lesions (facial papules, sometimes related to trichilemmoma; oral papillomatosis with cobblestone gingiva; acral keratoses)
- both dystrophic and adenomatous multinodular goiter
- intestinal tract polyps with variable histologies
- adenosis and fibrocystic disease of the breast
- macrocephaly
- lipomas
- genito-urinary abnormalities

Genes involved and Proteins

Location 10q23.31
Expression 403 amino-acids, phosphatase with tumor suppressive effects, negative regulator of the PI3K/Akt signal cell pathway by dephosphorylating PIP3
Germinal to date, at least 110 mutations have been described; they are observed along the various exons of the gene except the 9th (never described) and the 1st (very few reports); a mutational hot spot is observed in exon 5 in relation with the catalytic core motif; in the great majority of cases, inactivating mutations are observed, either by protein truncation, or by misense mutation within the phosphatase domain
