Genetic counseling and tumor predisposition in neuro-oncology practice.

Tumor predisposition syndromes may be under-recognized in neuro-oncology practice. Identifying patients with a hereditary tumor predisposition permits appropriate tumor management as well as surveillance and risk-reduction measures for patients and their families. The American College of Medical Genetics and Genomics and the National Society of Genetic Counselors recently published referral guidelines for tumor predisposition assessment, providing an impetus to review the use of genetic counseling in neuro-oncology and to describe features of the less stereotypic conditions from the perspective of neuro-oncology practice. This review also provides a framework for the identification and management of these conditions, as well as references to guidelines and resources for providers and patients.
