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

Classification made for transcript

Verdict is Likely_benign. Variant got -2 ACMG points.

PM2
Very rare variant in population databases, with high coverage;
PM4
Nonframeshift variant in NON repetitive region in NM_005534.4. Strenght limited to Supporting due to length of the change: 1aa.
BP6
Variant 21-33403590-TCGC-T is Benign according to our data. Variant chr21-33403590-TCGC-T is described in ClinVar as [Likely_benign]. Clinvar id is 3350397.Status of the report is no_assertion_criteria_provided, 0 stars.
BS1
Variant frequency is greater than expected in population sas. gnomad4_exome allele frequency = 0.000703 (852/1211410) while in subpopulation SAS AF= 0.0034 (190/55814). AF 95% confidence interval is 0.00301. There are 0 homozygotes in gnomad4_exome. There are 482 alleles in male gnomad4_exome subpopulation. This position pass quality control queck.
