Maturity Onset Diabetes of the Young (MODY): Deletion/Duplication Panel

Condition Description

Maturity-onset diabetes of the young (MODY) is defined by the clinical features of early-onset Type 2 (non-insulin-dependent) diabetes and an autosomal dominant inheritance. Pathogenic variants in four genes have been shown to cause MODY, with each having a defined clinical presentation. In the European Caucasian population, molecular analysis of these four genes is useful in confirming the clinical diagnosis of MODY and the prediction of the future clinical course.

Indications

This test is indicated for individuals with:
  • Confirmation of a clinical diagnosis of maturity-onset diabetes of the young (MODY).
  • Carrier testing in adults with a family history of hereditary maturity-onset diabetes of the young (MODY).

Methodology

Deletion/Duplication Analysis: DNA isolated from peripheral blood is hybridized to a gene-targeted CGH array to detect deletions and duplications. The targeted CGH array has overlapping probes that cover the entire genomic region.

Detection

Deletion/Duplication Analysis: Detection is limited to duplications and deletions. The CGH array will not detect point or intronic mutations. Results of molecular analysis must be interpreted in the context of the patient\'s clinical and/or biochemical phenotype.
