FBXO7 Y52C Polymorphism as a Potential Protective Factor in Parkinson's Disease.

Mutations in the F-box only protein 7 gene (FBXO7), the substrate-specifying subunit of SCF E3 ubiquitin ligase complex, cause Parkinson's disease (PD)-15 (PARK15). To identify new variants, we sequenced FBXO7 cDNA in 80 Taiwanese early onset PD patients (age at onset ≤50) and only two known variants, Y52C (c.155A>G) and M115I (c.345G>A), were found. To assess the association of Y52C and M115I with the risk of PD, we conducted a case-control study in a cohort of PD and ethnically matched controls. There w...

Follow-up of endometrial cancer.

Available data on appropriate follow-up in endometrial cancer highlight the need of well-conducted studies. Most recurrences tend to occur within three years and involve symptoms. Routine tests are not advocated without symptoms. In case of suspicious recurrence, TEP/CT seems to be the most sensitive and specific method. There is limited evidence to decide whether follow-up schedules with multiple visits result in survival benefits. An appropriate follow-up should be discussed based upon the risk of recurre...
