Since reduced insulin-stimulated glucose uptake and reduced glucose-6-phosphate content in muscle have been demonstrated in pre-non-insulin-dependent diabetes mellitus (pre-NIDDM) and NIDDM subjects, we have examined the coding region of the HKII gene in NIDDM patients to determine whether these patients show genetic polymorphisms that are associated with or contribute to the disease. Single-strand conformational polymorphism analysis and nucleotide sequencing were initially performed on the entire coding region of the HKII gene of 38 insulin-resistant NIDDM patients and 5 healthy control subjects. This analysis revealed four missense mutations at codons 142 (Gln to His), 148 (Leu to Phe), 497 (Arg to Gln), and 844 (Arg to Lys) and an additional six exon polymorphisms that did not predict any change in amino acid composition of the protein.
