St. Luke's Children's Genetics Clinic

At St. Luke's Children's Genetics Clinic, we serve children and adults seeking diagnosis and management of genetic conditions. We provide counseling regarding inheritance risks, rare disease support, informed genetic testing, and interpretation of test results. 

Our goal is to help patients get the comprehensive medical care they need, working in partnership with the patient and family, their primary care provider, and other specialists. 

Genetics clinics are held five days each month, by appointment, at St. Luke's Children's Specialty Center in Boise. Children are evaluated and cared for by our certified genetic counselors, Brittney Knysezek, MS, GC and Rachel Westman, MS, GC.

In addition, our genetic counselors are available for consultation Monday through Friday, from 8 a.m. to 4:30 p.m. Pease call (208) 381-7339 for consultation, to refer a patient, or to schedule an appointment.
