A polymorphic microsatellite in intron 6 of the human proteasome core particle PSMA6 gene (HSMS006), and four other microsatellites localized upstream on human chromosome 14q13.2 (HSMS801, HSMS702, HSMS701, HSMS602), were genotyped in 104 type 2 diabetic patients and 129 age-matched control subjects from Latvia and replicated in 91 type 2 diabetic patients and 88 age-matched healthy control subjects from the Botnia Study in Finland. In type 2 diabetic patients from both populations the HSMS006 (TG)22 allele was two times more frequent compared to the control group. In the Latvian population the (CAA)8 allele of the HSMS602 marker was less frequent in the diabetic group, as was the (AC)24 allele of microsatellite HSMS801. Allele frequencies of the HSMS701 and 702 repeats were similar in healthy controls and type 2 diabetic patients. In conclusion, our data suggest that variants in the PSMA6 gene on chromosome 14q13.2 are associated with type 2 diabetes.

In our preceding studies we have identified microsatellite polymorphisms inside the PSMA6 gene and in its 5' upstream region. Following the observed associations of microsatellite polymorphisms with non-insulin dependent diabetes mellitus and Graves' disease we extended the evaluation of PSMA6 genetic variations to cardiovascular disorders and non-insulin dependent diabetes mellitus. New polymorphisms in the promoter region and exon 6 of the gene were identified by direct sequencing of the promoter region and all seven exons of the gene in 30 individuals of European descent. Two SNPs at positions -110 and -8 from the translation start, in the promoter region and 5'UTR respectively, were analyzed. Neither polymorphism was associated with the risk of myocardial infarction. No significant association of the polymorphisms with plasma lipid levels or BMI was observed. A borderline association of both polymorphisms with diastolic blood pressure was observed in the control group. Genotype -8CG was significantly more frequent in type 2 diabetes patients, and haplotype C-110/G-8, compared to C-110/C-8 was associated with a higher risk of NIDDM.

The proteasome is a large, multiple subunit complex that is capable of degrading most intracellular proteins. Polymorphisms in proteasome subunits are associated with cardiovascular diseases, diabetes, neurological diseases, and cancer. One polymorphism in the proteasome gene PSMA6 (-8C/G) is associated with three different diseases: type 2 diabetes, myocardial infarction, and coronary artery disease. One type of proteasome, the immunoproteasome, which contains inducible catalytic subunits, is adapted to generate peptides for antigen presentation. It has recently been shown that mutations and polymorphisms in the immunoproteasome catalytic subunit PSMB8 are associated with several inflammatory and autoinflammatory diseases including Nakajo-Nishimura syndrome, CANDLE syndrome, and intestinal M. tuberculosis infection. This comprehensive review describes the disease-related polymorphisms in proteasome genes associated with human diseases and the physiological modulation of proteasome function by these polymorphisms. Given the large number of subunits and the central importance of the proteasome in human physiology as well as the fast pace of detection of proteasome polymorphisms associated with human diseases, it is likely that other polymorphisms in proteasome genes associated with diseases will be detected in the near future. While disease-associated polymorphisms are now readily discovered, the challenge will be to use this genetic information for clinical benefit.
