Genes affected

IFNGR2 (HGNC:5440): (interferon gamma receptor 2) This gene (IFNGR2) encodes the non-ligand-binding beta chain of the gamma interferon receptor. Human interferon-gamma receptor is a heterodimer of IFNGR1 and IFNGR2. Defects in IFNGR2 are a cause of mendelian susceptibility to mycobacterial disease (MSMD), also known as familial disseminated atypical mycobacterial infection. MSMD is a genetically heterogeneous disease with autosomal recessive, autosomal dominant or X-linked inheritance. [provided by RefSeq, Jul 2008]

ACMG classification

Verdict is Uncertain_significance. Variant got 5 ACMG points.

• PM1: In a disulfide_bond (size 25) in uniprot entity INGR2_HUMAN there are 4 pathogenic changes around while only 1 benign (80%) in NM_005534.4
• PM4: Nonframeshift variant in NON repetitive region in NM_005534.4.
• PP5: Variant 21-33432274-AAAGTAACATCTTTAGAGTCGGGCATTT-A is Pathogenic according to our data. Variant chr21-33432274-AAAGTAACATCTTTAGAGTCGGGCATTT-A is described in ClinVar as [Pathogenic]. Clinvar id is 14728.Status of the report is no_assertion_criteria_provided, 0 stars. Variant chr21-33432274-AAAGTAACATCTTTAGAGTCGGGCATTT-A is described in Lovd as [Pathogenic].
