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.
