Genes affected

IFI30 (HGNC:5398): (IFI30 lysosomal thiol reductase) The protein encoded by this gene is a lysosomal thiol reductase that at low pH can reduce protein disulfide bonds. The enzyme is expressed constitutively in antigen-presenting cells and induced by gamma-interferon in other cell types. This enzyme has an important role in MHC class II-restricted antigen processing. [provided by RefSeq, Jul 2008]

The c.304G>A (p.G102R) alteration is located in exon 2 (coding exon 2) of the IFI30 gene. This alteration results from a G to A substitution at nucleotide position 304, causing the glycine (G) at amino acid position 102 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
