Presenilin 1 Glu318Gly polymorphism: interpret with caution.

BACKGROUND: The significance of the presenilin 1 (PSEN1) Glu318Gly polymorphism has been described as either a causal mutation with reduced penetrance or a benign polymorphism. When this polymorphism is found in a symptomatic person with a family history of dementia, counseling on recurrence risk becomes very problematic. OBJECTIVE: To demonstrate that the PSEN1 Glu318Gly polymorphism should be interpreted cautiously. DESIGN: Case histories of 2 patients with presenile dementia and family histories of dementia are described. The PSEN1 gene was sequenced in the patients and in 11 family members of patient 1. RESULTS: Two patients with presenile dementia and personality change were found to carry the PSEN1 Glu318Gly polymorphism. The presence of the polymorphism was confirmed in several family members of patient 1 but was absent in 1 symptomatic relative. CONCLUSIONS: The Glu318Gly polymorphism may be associated with risk for neurodegenerative disease; however, in the cases described here, it did not appear to be a risk factor. Until there is consensus on whether it is associated with disease, families should be informed that the clinical significance of the polymorphism is uncertain.[1]
