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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJun 16, 2024The c.436A>G (p.I146V) alteration is located in exon 4 (coding exon 4) of the IFI30 gene. This alteration results from a A to G substitution at nucleotide position 436, causing the isoleucine (I) at amino acid position 146 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
