Background:
Maturity-onset diabetes of the young (MODY) is a monogenic form of diabetes that results from mutations of one of a group of genes which affect the insulin-producing ability of the pancreas. This condition is characterized by childhood to early onset of diabetes. This condition is inherited in an autosomal dominant manner.
Reasons for Referral:
- Molecular diagnosis for individuals with suspected forms of diabetes
- Carrier testing
Methodology:
Next generation sequencing will analyze the exons or coding regions of 25 Diabetes of Young-Maturity Onset-associated genes using Illumina NextSeq 500 technology and preparing samples using hybridization probes to enrich exonic regions. Promoter, intronic, etc. regions are not assessed on our assay, but may contain variants that impact gene function.
Diabetes of Young-Maturity Onset (25 genes): ABCC8, AKT2, BLK, CISD2, CP, EIF2AK3, FOXP3, GATA6, GCK, GLIS3, HNF1A, HNF1B, HNF4A, IER3IP1, INS, KCNJ11, KLF11, NEUROD1, NEUROG3, PAX4, PDX1, PTF1A, RFX6, SLC2A2, WFS1
