| Identified Mutation |
TYR1122TER |
| Remarks |
Clinically affected; hirsutism; cardiomyopathy; died at age 3 months; increased circulating insulin levels (above 6000 pmol/liter); reduced insulin binding; donor subject is a compound heterozygote: one allele has a T>A transversion of the INSR gene resulting in a substitution of glutamine for leucine at codon 93 [Leu93Gln(L93Q)] and a second allele has a C>A transversion of the INSR gene resulting in a substitution of a stop codon for a tyrosine at codon 1122 [Tyr1122Stop(Y1122X)]. |
