Testing strategy


First, we will test for the requested condition. Upon determination of the presence of a disease-related mutation, we can perform targeted-mutation analysis on additional family members upon the request of that additional family member's health-care provider/genetic counselor. Targeted mutation analysis may also be performed for couples considering having children, where one member of the couple is a known carrier of a causal mutation.Testing must be requested by that member's health-care provider.

How to order


Send at least 5ml of whole (peripheral) blood in an EDTA purple-capped anticoagulant tube at room temperature. Fill out order and consent forms (links are at top right of the webpage). Extracted DNA is accepted as well. Appropriate billing mechanism should be established prior to submitting specimen for testing (see "order form" link at top right of lab webpage).
