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]

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 19, 2024The c.710G>C (p.C237S) alteration is located in exon 7 (coding exon 7) of the IFI30 gene. This alteration results from a G to C substitution at nucleotide position 710, causing the cysteine (C) at amino acid position 237 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
