Together, the disorders caused by PTEN mutations are called PTEN hamartoma tumor syndromes, or PHTS. Mutations responsible for these syndromes cause the resulting protein to be non-functional or absent. The defective protein allows the cell to divide in an uncontrolled way and prevents damaged cells from dying, which can lead to the growth of ...
The genetics of the Bannayan–Riley–Ruvalcaba syndrome is determined, in the majority of cases, via the PTEN gene which presents about 30 mutations in this condition. This gene which regulates cell growth , when not working properly can lead to hamartomas.
The most common known aberrations include the PIK3CA gene mutation and the loss-of-function mutations or epigenetic silencing of PTEN. [12] The phosphoinositide 3-kinase (PI3K)/protein kinase B (Akt)/mammalian target of rapamycin (mTOR) pathway is activated in approximately 30–40% of BC cases.
For those with endocrine issues (low levels of thyrotropin [a pituitary hormone responsible for regulating thyroid hormones], follicle stimulating hormone) drug therapy is recommended. For those who are disturbed by the appearance of lentigines, cryosurgery may be beneficial. Due to the large number of lentigines this may prove time-consuming.
Many of these mutations cause the kinase to be more active. It is the single most mutated kinase in glioblastoma , the most malignant primary brain tumor. [ 22 ] The PtdIns(3,4,5) P 3 phosphatase PTEN that antagonises PI3K signaling is absent from many tumours.

Antileukemic drugs, anticancer drugs that are used to treat one or more types of leukemia, include: [1] 6-Mercaptopurine; 6-Thioguanine; Arsenic trioxide; Asparaginase;
Given these poor remission and survival rates, other treatments have been added to the initial treatment regimens. Studies have shown that the addition of intrathecally administered drugs (administered directly into the spinal canal ) as prophylaxis prolongs the period of CNS-free disease and increases overall survival.
