Disease Linkage
General Disease Association:
Neurological disorders
Specific Diseases (Non-cancerous):
Amyotrophic lateral sclerosis (ALS); Primary lateral sclerosis (PLS)
Comments:
ALS is a rare neuronal disease affecting motor control. PFTAIRE2 may be associated with amyotrophic lateral sclerosis 2 (ALS2), which is an autosomal recessive form of juvenile ALS. Characteristics of ALS can include cramping, stiffness, muscle twitching, weakness, slurring words, chewing difficulties, and dysphagia (difficulty swallowing). Lateral Sclerosis (PLS) is a rare neuronal disease related to the Amyotrophic Lateral Sclerosis disorder.
Gene Expression in Cancers:
The COSMIC website notes an up-regulated expression score for PFTAIRE2 in diverse human cancers of 300, which is 0.7-fold of the average score of 462 for the human protein kinases. The down-regulated expression score of 0 for this protein kinase in human cancers was 100% lower than the average score of 60 for the human protein kinases.
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: 0.08 % in 25141 diverse cancer specimens. This rate is very similar (+ 6% higher) to 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: 0.34 % in 1270 large intestine cancers tested; 0.31 % in 1634 lung cancers tested; 0.29 % in 548 urinary tract cancers tested; 0.27 % in 603 endometrium cancers tested; 0.16 % in 864 skin cancers tested; 0.16 % in 589 stomach cancers tested; 0.12 % in 1316 breast cancers tested; 0.09 % in 1512 liver cancers tested; 0.09 % in 1276 kidney cancers tested; 0.04 % in 558 thyroid cancers tested; 0.03 % in 833 ovary cancers tested; 0.02 % in 1459 pancreas cancers tested; 0.01 % in 2082 central nervous system cancers tested.
Frequency of Mutated Sites:
Most frequent mutations with the number of reports indicated in brackets: V210M (3).
Comments:
Only 3 deletions, and no insertions or complex mutations are noted on the COSMIC website.
