Genes affected

CD14 (HGNC:1628): (CD14 molecule) The protein encoded by this gene is a surface antigen that is preferentially expressed on monocytes/macrophages. It cooperates with other proteins to mediate the innate immune response to bacterial lipopolysaccharide, and to viruses. This gene has been identified as a target candidate in the treatment of SARS-CoV-2-infected patients to potentially lessen or inhibit a severe inflammatory response. Alternative splicing results in multiple transcript variants encoding the same protein. [provided by RefSeq, Aug 2020]

The c.206T>G (p.F69C) alteration is located in exon 3 (coding exon 2) of the CD14 gene. This alteration results from a T to G substitution at nucleotide position 206, causing the phenylalanine (F) at amino acid position 69 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
