Variant summary

Our verdict is Likely pathogenic. Variant got 9 ACMG points: 9P and 0B. PM1 PM2 PP3_Strong PP5

The NM_012275.3(IL36RN):​c.368C>G​(p.Thr123Arg) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.000000684 in 1,461,618 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a pathogenic outcome for this variant. Variant has been reported in ClinVar as Pathogenic (no stars). Synonymous variant affecting the same amino acid position (i.e. T123T) has been classified as Benign.

Genes affected

IL36RN (HGNC:15561): (interleukin 36 receptor antagonist) The protein encoded by this gene is a member of the interleukin 1 cytokine family. This cytokine was shown to specifically inhibit the activation of NF-kappaB induced by interleukin 1 family, member 6 (IL1F6). This gene and eight other interleukin 1 family genes form a cytokine gene cluster on chromosome 2. Two alternatively spliced transcript variants encoding the same protein have been reported.

ACMG classification

Verdict is Likely_pathogenic. Variant got 9 ACMG points.

• PM1: In a disulfide_bond (size 146) in uniprot entity I36RA_HUMAN there are 6 pathogenic changes around while only 2 benign (75%) in NM_012275.3
• PM2: Very rare variant in population databases, with high coverage
• PP3: MetaRNN computational evidence supports a deleterious effect, 0.978
• PP5: Variant 2-113062577-C-G is Pathogenic according to our data. Variant chr2-113062577-C-G is described in ClinVar as [Pathogenic]. Clinvar id is 40006.Status of the report is no_assertion_criteria_provided, 0 stars. Variant chr2-113062577-C-G is described in Lovd as [Likely_pathogenic].
