Variant summary

Our verdict is Pathogenic. Variant got 11 ACMG points: 11P and 0B. PM1 PM2 PM5 PP3_Strong PP5

The ENST00000367739.9(IFNGR1):​c.230G>A​(p.Cys77Tyr) variant causes a missense change. The variant was absent in control chromosomes in GnomAD project. In-silico tool predicts a pathogenic outcome for this variant. Variant has been reported in ClinVar as Pathogenic (no stars). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. C77F) has been classified as Likely pathogenic.

Genes affected

IFNGR1 (HGNC:5439): (interferon gamma receptor 1) This gene (IFNGR1) encodes the ligand-binding chain (alpha) of the gamma interferon receptor. Human interferon-gamma receptor is a heterodimer of IFNGR1 and IFNGR2. A genetic variation in IFNGR1 is associated with susceptibility to Helicobacter pylori infection. In addition, defects in IFNGR1 are a cause of mendelian susceptibility to mycobacterial disease, also known as familial disseminated atypical mycobacterial infection. [provided by RefSeq, Jul 2008]

ACMG classification

Verdict is Pathogenic. Variant got 11 ACMG points.

• PM1: In a disulfide_bond (size 8) in uniprot entity INGR1_HUMAN there are 6 pathogenic changes around while only 0 benign (100%) in ENST00000367739.9
• PM2: Very rare variant in population databases, with high coverage
• PM5: Other missense variant is known to change same aminoacid residue: Variant chrnull-null-null-null is described in UniProt as null.
• PP3: MetaRNN computational evidence supports a deleterious effect, 0.987
• PP5: Variant 6-137206279-C-T is Pathogenic according to our data. Variant chr6-137206279-C-T is described in ClinVar as [Pathogenic]. Clinvar id is 17949.Status of the report is no_assertion_criteria_provided, 0 stars. Variant chr6-137206279-C-T is described in Lovd as [Pathogenic].
