Inborn errors of type I IFN immunity in patients with life-threatening COVID-19

Qian Zhang, +172 more
- 23 Oct 2020 - 
TL;DR: The COVID Human Genetic Effort established to test the general hypothesis that life-threatening COVID-19 in some or most patients may be caused by monogenic inborn errors of immunity to SARS-CoV-2 with incomplete or complete penetrance finds an enrichment in variants predicted to be loss-of-function (pLOF), with a minor allele frequency <0.001.
Journal ArticleDOI

Autoantibodies neutralizing type I IFNs are present in ~ 4% of uninfected individuals over 70 years old and account for ~ 20% of COVID-19 deaths.

Paul Bastard, +58 more
- 19 Aug 2021 - 
TL;DR: In this paper, the authors found that auto-antibodies neutralizing high concentrations (10 ng/mL, in plasma diluted 1 to 10) of IFN-α and/or -ω are found in about 10% of patients with critical COVID-19 pneumonia, but not in subjects with asymptomatic infections.
Journal ArticleDOI

X-linked recessive TLR7 deficiency in ~1% of men under 60 years old with life-threatening COVID-19.

Takaki Asano, +66 more
- 19 Aug 2021 - 
TL;DR: This article reported very rare, biochemically deleterious X-linked TLR7 variants in 16 unrelated male individuals aged 7 to 71 years (mean: 36.7 years) from a cohort of 1,202 male patients aged 0.5 to 99 years with unexplained critical COVID-19 pneumonia.
Journal ArticleDOI

Human genetic and immunological determinants of critical COVID-19 pneumonia

Qian Zhang, +160 more
- 28 Jan 2022 - 
TL;DR: In this article , the molecular and cellular determinants of critical COVID-19 pneumonia were reviewed and the TLR3- and TLR7-dependent production of type I interferons by respiratory epithelial cells and plasmacytoid dendritic cells, respectively, is essential for host defence against SARS-CoV-2 infection.
Journal ArticleDOI

Preexisting autoantibodies to type I IFNs underlie critical COVID-19 pneumonia in patients with APS-1.

Paul Bastard, +86 more
TL;DR: In this paper, the authors report 22 APS-1 patients from 21 kindreds in seven countries, aged between 8 and 48 yr and infected with SARS-CoV-2 since February 2020.
