Simonen et al1 found that 1 week after obtaining the results of genetic risk for type 1 diabetes in newborns, 55% of mothers and 37% of fathers of high-risk infants expressed modest worry. Although one really wants to know about risk over a lifetime and its effect on parent-child relationships,2,3 the data are cause for concern. Recall that a diagnosis of high-risk genotype confers between a 3% and 7% risk of developing type 1 diabetes, which is “4 to 10 times higher than the background population but still rather small.”1 Further recall that there are no current preventive therapies.
