Predictive risk information for patient and/or family members

Target population: Help
Individuals exhibiting symptoms consistent with Frontotemporal Dementia. Individuals with family history of FTD who would like to determine their risk of inheritance. Incidence of mutations in the PGRN gene is approximately up to 50 - 70%.
Variant Interpretation:
What is the protocol for interpreting a variation as a VUS? Help
HGMD, Disease specific databases and an Internal Variant Database are used for variant interpretation. An assessment is also made with a splice site predictor program. Once established as a VUS, Polyphen and SIFT analyses are performed to help provide an interpretation.

Are family members with defined clinical status recruited to assess significance of VUS without charge? Help
Yes.

Will the lab re-contact the ordering physician if variant interpretation changes? Help
Yes. Ordering physician or genetic counselor contacted and a revised report issued.
