Disease Linkage

General Disease Association:

Genetic disorders
Specific Diseases (Non-cancerous):

Tuberous sclerosis; Tuberous sclerosis complex
Comments:
Tuberous sclerosis is a rare genetic disease characterized by the growth of benign tumours (non-cancerous) in the brain and other organs. Symptoms are variable dependent upon location of tumour growth. Common symptoms include light-coloured patches of skin, areas of thickened skin, and tumour growth under the nails. This disease is inherited in an autosomal dominant manner. Known mutations in p70S6K are associated with a gain-of-function phenotype through the facilitation of phosphorylation by the upstream kinase PDPK1. These mutations are associated with tuberous sclerosis, potentially through the over-stimulation of cell growth and proliferation leading to aberrant proliferation of cells.
 
Gene Expression in Cancers:

TranscriptoNET (www.transcriptonet.ca) analysis with mRNA expression data retrieved from the National Center for Biotechnology Information's Gene Expression Omnibus (GEO) database, which was normalized against 60 abundantly and commonly found proteins, indicated altered expression for this protein kinase as shown here as the percent change from normal tissue controls (%CFC) as supported with the Student T-test in the following types of human cancers: Barrett's esophagus epithelial metaplasia (%CFC= -45, p<0.059); Cervical cancer (%CFC= +116, p<0.006); Clear cell renal cell carcinomas (cRCC) stage I (%CFC= +602, p<0.0001); Ovary adenocarcinomas (%CFC= +166, p<0.031); Pituitary adenomas (ACTH-secreting) (%CFC= -45); Prostate cancer - primary (%CFC= -87, p<0.0001); and Uterine leiomyomas from fibroids (%CFC= +66, p<0.035). The COSMIC website notes an up-regulated expression score for p70S6K in diverse human cancers of 766, which is 1.7-fold of the average score of 462 for the human protein kinases. The down-regulated expression score of 256 for this protein kinase in human cancers was 4.3-fold of the average score of 60 for the human protein kinases.
Mutagenesis Experiments:

Insertional mutagenesis studies in mice support a role for this protein kinase in mouse cancer oncogenesis.
Mutation Rate in All Cancers:

Percent mutation rates per 100 amino acids length in human cancers: 0.05 % in 25555 diverse cancer specimens. This rate is only -35 % lower than the average rate of 0.075 % calculated for human protein kinases in general.
Mutation Rate in Specific Cancers:

Highest percent mutation rates per 100 amino acids length in human cancers: 0.2 % in 1119 large intestine cancers tested; 0.13 % in 1942 lung cancers tested.
Frequency of Mutated Sites:

None > 4 in 20,718 cancer specimens
Comments:
Only 2 deletions, 1 insertion, and no complex mutations are noted on the COSMIC website.
