Prevalence of TAU mutations in an Italian clinical series of familial frontotemporal patients

Frontotemporal dementia (FTD) is a clinical entity grouping different diagnostic conditions. FTD can occur in a sporadic form; however in 30-50% of cases a familial form of FTD has been observed. Mutations in the TAU gene were associated to familial FTD linked to chromosome 17. Our aim was to investigated the proportion of FTD cases attributable to TAU gene mutations in an Italian clinical series. We analyzed 38 patients with FTD; of these, 13 had a positive family history of FTD. All TAU gene exons and flanking intronic regions were sequenced. In our familial FTD sample the estimation of TAU gene mutations accounted for a relative low prevalence (7.6%); based on our results we could argue the existence of other mutations in regulatory regions in the TAU gene or, on the other hand, other genes might be responsible for the most cases of familial FTD.

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Synthetic Genetic Array Analysis

Synthetic genetic arrays allow the systematic examination of genetic interactions. Here is the latest research focusing on synthetic genetic arrays and their analyses.

Position Effect Variegation

Position Effect Variagation occurs when a gene is inactivated due to its positioning near heterochromatic regions within a chromosome. Discover the latest research on Position Effect Variagation here.

Head And Neck Squamous Cell Carcinoma

Squamous cell carcinomas account for >90% of all tumors in the head and neck region. Head and neck squamous cell carcinoma incidence has increased dramatically recently with little improvement in patient outcomes. Here is the latest research on this aggressive malignancy.
