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.463A>T (p.M155L) alteration is located in exon 4 (coding exon 4) of the IFI30 gene. This alteration results from a A to T substitution at nucleotide position 463, causing the methionine (M) at amino acid position 155 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
