▶Variants in interferon‐alpha pathway genes and response to pegylated interferon‐Alpha2a plus ribavirin for treatment of chronic hepatitis C virus infection in the hepatitis C antiviral long‐term treatment against cirrhosis trial†‡AssociationN=712Tania Mara Welzel et al.(2009)· Hepatology
In the HALT-C trial of 581 European American patients with advanced chronic hepatitis C, genetic variants in the interferon-alpha pathway were associated with sustained virological response (SVR) to pegylated interferon-alpha-2a plus ribavirin therapy. Key associations included IFNAR1 IVS1-22G (aOR=0.57, p=0.02), IFNAR2 Ex2-33C (aOR=2.09, p=0.02), JAK1 IVS22+112T (aOR=1.66, p=0.04), and ADAR Ex9+14A (aOR=1.67, p=0.03). The TYK2 -2256A promoter variant showed a borderline association in European Americans (OR=1.51, p=0.05) but a strong association in African American patients (p=0.006).
About JAK1
This gene encodes a membrane protein that is a member of a class of protein-tyrosine kinases (PTK) characterized by the presence of a second phosphotransferase-related domain immediately N-terminal to the PTK domain. The encoded kinase phosphorylates STAT proteins (signal transducers and activators of transcription) and plays a key role in interferon-alpha/beta, interferon-gamma, and cytokine signal transduction. This gene plays a crucial role in effecting the expression of genes that mediate inflammation, epithelial remodeling, and metastatic cancer progression. This gene is a key component of the interleukin-6 (IL-6)/JAK1/STAT3 immune and inflammation response and is a therapeutic target for alleviating cytokine storms. The kinase activity of this gene is directly inhibited by the suppressor of cytokine signalling 1 (SOCS1) protein. Alternative splicing results in multiple transcript variants.
