Abstract

As genotyping for Lynch syndrome has become widespread, more and more people are being counseled about whether to be genotyped for mutations in mismatch repair genes. Recently a number of quantitative models have been developed to identify potential Lynch syndrome patients and serve as decision aids for patients at genetic counseling clinics. In contrast to existing clinical guidelines that give dichotomous classifications, these models provide a probability that a family or individual has Lynch syndrome. These models have been shown to be useful tools in identifying likely carriers of Lynch syndrome mutations. Correctly used, they have the potential to greatly improve the current diagnosis and management of Lynch syndrome families. To help clinicians and genetic counseling professionals understand the differences among these models and use the models wisely, we review the key features of each model and offer some guidelines on their use.
