Disease Linkage
General Disease Association:
Neurological disorders
Specific Diseases (Non-cancerous):
Limbic encephalitis
Comments:
Mutations on multiple sites can be either activatory or inhibitory on BRSK2's phosphotransferase activity. Example of diseases that may be associated with BRSK2 are limbic encephalitis and small-cell lung cancer (SCLC). BRSK2 may be an autoantigen involved in the pathogenesis of SCLC-associated limbic encephalitis and SCLC patients with paraneoplastic neurological syndromes have been reported to have antibodies against BRSK2 (PubMed:16165222).
Mutagenesis Experiments:
Insertional mutagenesis studies in mice have not yet revealed 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 24434 diverse cancer specimens. This rate is -40 % 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: 0.31 % in 864 skin cancers tested; 0.25 % in 273 cervix cancers tested; 0.14 % in 1229 large intestine cancers tested.
Frequency of Mutated Sites:
None > 2 in 20,009 cancer specimens
Comments:
Only 3 deletions, 2 insertions, and no complex mutations are noted on the COSMIC website.
