Chlorpropamide-alcohol flushing is not useful for individual genetic counseling of diabetic patients

The presence or absence of chlorpropamide-alcohol flushing (CPAF) was not correlated with the classification of diabetes. Five out of twelve patients with juvenile-onset diabetes (JOD) flushed and three out of four patients with maturity-onset diabetes in young people (MODY) did not flush. Consequently, CPAF cannot be used for individual genetic counseling in diabetes mellitus.
