Platelets Can Associate with SARS-Cov-2 RNA and Are Hyperactivated in COVID-19.

In addition to the overwhelming lung inflammation that prevails in COVID-19, hypercoagulation and thrombosis contribute to the lethality of subjects infected with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Platelets are chiefly implicated in thrombosis. Moreover, they can interact with viruses and are an important source of inflammatory mediators.

Mutation Analysis of Consanguineous Moroccan Patients with Parkinson's Disease Combining Microarray and Gene Panel.

During the last two decades, 15 different genes have been reported to be responsible for the monogenic form of Parkinson's disease (PD), representing a worldwide frequency of 5-10%. Among them, 10 genes have been associated with autosomal recessive PD, with and being the most frequent. In a cohort of 145 unrelated Moroccan PD patients enrolled since 2013, 19 patients were born from a consanguineous marriage, of which 15 were isolated cases and 4 familial.

Evidence for prehistoric origins of the G2019S mutation in the North African Berber population.

The most common cause of the monogenic form of Parkinson's disease known so far is the G2019S mutation of the leucine-rich repeat kinase 2 (LRRK2) gene. Its frequency varies greatly among ethnic groups and geographic regions ranging from less than 0.1% in Asia to 40% in North Africa.

G2019S Mutation: Prevalence and Clinical Features in Moroccans with Parkinson's Disease.

. The G2019S mutation is the most common genetic determinant of Parkinson's disease (PD) identified to date. This mutation, reported in both familial and sporadic PD, occurs at elevated frequencies in Maghreb population.
