600281.0001; MATURITY-ONSET DIABETES OF THE YOUNG, TYPE I; MODY1 |
| Identified Mutation |
GLN268TER; In the historic R-W pedigree in which Fajans (1989) defined type 1 maturity-onset diabetes of the young (MODY1; 125850), Yamagata et al. (1996) found a a C-to-T substitution in codon 268 of the TCF14 gene that generated a CAG-to-TAG (Q268X) nonsense mutation. Some subjects in the R-W pedigree had inherited the Q268X mutation but were not yet diabetic; in addition, there were subjects in the pedigree who had noninsulin-dependent diabetes mellitus but did not inherit the Q268X mutation or at-risk haplotype. In one case, NIDDM had been diagnosed at the age of 48 years, and the patient was hyperinsulinemic, indicating that this was probably late-onset NIDDM rather than MODY. The patient had 6 children, 1 of whom also had NIDDM; another child had impaired glucose tolerance, and all had only normal alleles at the TCF14 locus.

| Remarks |
MODY; fasting hyperglycemia; diagnosed at age 14; daughter of GM08106; donor subject has a C>T substitution at codon 268 in exon 7 of the HNF4A (TCF14) gene that results in a CAG>TAG nonsense mutation [Gln268Ter (Q268X)]; donor subject also has a missense polymorphism of the HNF4A (TCF14) gene: a C>T transition at nucleotide 609 in exon 4 (609C>T) resulting in a threonine to isoleucine change at codon 130 [Thr130Ile (T130I)] |
