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.572A>C (p.N191T) alteration is located in exon 5 (coding exon 5) of the IFI30 gene. This alteration results from a A to C substitution at nucleotide position 572, causing the asparagine (N) at amino acid position 191 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
