Implication of IL-12A, IL-12B, IL-6, and TNF single-nucleotide polymorphisms in severity and susceptibility to COVID-19.

Background: The Coronavirus Disease 2019 (COVID-19) pandemic has led to significant global morbidity and mortality. Understanding the genetic factors that influence disease outcomes can provide critical insights into pathogenesis and potential therapeutic targets.

Objective: This study aimed to investigate the potential correlation between single nucleotide polymorphisms (SNPs) in , , , and genes and the severity as well as susceptibility to COVID-19 among Moroccan patients.

TYK2, IFITM3, IFNAR2 and OAS3 single-nucleotide polymorphisms among severe COVID-19 ICU patients in Morocco.

Objectives: This study aimed to explore the potential correlation between specific single nucleotide polymorphisms (TYK2, IFITM3, IFNAR2, and OAS3 variants) and the severity of COVID-19 in Moroccan patients.

Methods: A genetic analysis was conducted on 109 patients with PCR-confirmed SARS-CoV-2 infection in Morocco. Among these patients, 46% were hospitalized in the intensive care unit, while 59% were not hospitalized.

Clinical Significance of Somatic Mutations in RAS/RAF/MAPK Signaling Pathway in Moroccan and North African Colorectal Cancer Patients.

Background: Mutations in RAS (KRAS, NRAS) and BRAF genes are the main biomarker predicting response to anti-EGFR monoclonal antibodies in targeted therapy in colorectal cancer (CRC).

Objective: Our study aims to evaluate the frequencies of KRAS, NRAS and BRAF mutations and their possible associations with clinico-pathological features in CRC patients from Morocco.

Methods: DNA was extracted from 80 FFPE samples using the QIAamp DNA FFPE-kit.

Coding-Complete Sequence of a SARS-CoV-2 Strain from an Omicron (B.1.1.529+BA.1) Variant Detected in Morocco.

Here, we describe the coding-complete sequence of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) strain HM36, identified as a strain of concern of B.1.1.
