Disease Linkage
General Disease Association:
Cornea, and blood vessel disorders
Specific Diseases (Non-cancerous):
Corneal endothelial dystrophy 2, autosomal recessive; Congenital hereditary endothelial dystrophy Type 1
Comments:
Corneal Endothelial Dystrophy 2, Autosomal Recessive is a heritable recessive disorder involving endotheliitis (inflammation of blood vessels) and corneal dystrophy (deposition of substances in cornea). Congenital Hereditary Endothelial Dystrophy Type I is a dominant inherited disorder involving endotheliitis (inflammation of blood vessels).
Comments:
CHED levels are up-regulated 1.7-fold in human tumours compared to most other protein kinases.
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: Brain oligodendrogliomas (%CFC= -57, p<0.098); Clear cell renal cell carcinomas (cRCC) stage I (%CFC= +728, p<0.003); and Prostate cancer - primary (%CFC= -61, p<0.0001). The COSMIC website notes an up-regulated expression score for CHED in diverse human cancers of 801, which is 1.7-fold of the average score of 462 for the human protein kinases. The down-regulated expression score of 234 for this protein kinase in human cancers was 3.9-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 24939 diverse cancer specimens. This rate is only -29 % 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: 0.66 % in 10 peritoneum cancers tested; 0.21 % in 1270 large intestine cancers tested; 0.18 % in 864 skin cancers tested; 0.18 % in 589 stomach cancers tested; 0.15 % in 603 endometrium cancers tested; 0.12 % in 273 cervix cancers tested; 0.09 % in 710 oesophagus cancers tested; 0.08 % in 1634 lung cancers tested; 0.05 % in 1512 liver cancers tested.
Frequency of Mutated Sites:
None > 5 in 20,224 cancer specimens
Comments:
Ten deletions, no insertions and 1 complex mutation are noted on the COSMIC website.
