Variant summary

Our verdict is Pathogenic. Variant got 10 ACMG points: 10P and 0B. PM1 PM2 PM5 PP3_Strong

The NM_001142784.3(IL11RA):​c.662C>T​(p.Pro221Leu) 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. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar. Another variant affecting the same amino acid position, but resulting in a different missense (i.e. P221R) has been classified as Likely pathogenic.

• Frequency: Genomes: not found (cov: 32)
• Consequence: IL11RA NM_001142784.3 missense
• Clinical Significance: Not reported in ClinVar
• Conservation: PhyloP100: 5.29

Genes affected

IL11RA (HGNC:5967): (interleukin 11 receptor subunit alpha) Interleukin 11 is a stromal cell-derived cytokine that belongs to a family of pleiotropic and redundant cytokines that use the gp130 transducing subunit in their high affinity receptors. This gene encodes the IL-11 receptor, which is a member of the hematopoietic cytokine receptor family. This particular receptor is very similar to ciliary neurotrophic factor, since both contain an extracellular region with a 2-domain structure composed of an immunoglobulin-like domain and a cytokine receptor-like domain. Multiple alternatively spliced transcript variants have been found for this gene. [provided by RefSeq, Jun 2012]

ACMG classification

Verdict is Pathogenic. Variant got 10 ACMG points.

• PM1: In a domain Fibronectin type-III 2 (size 97) in uniprot entity I11RA_HUMAN there are 7 pathogenic changes around while only 2 benign (78%) in NM_001142784.3
• PM2: Very rare variant in population databases, with high coverage
• PM5: Other missense variant is known to change same aminoacid residue: Variant chr9-34658535-C-G is described in ClinVar as [Likely_pathogenic]. Clinvar id is 30137.Status of the report is criteria_provided_single_submitter, 1 stars.
• PP3: MetaRNN computational evidence supports a deleterious effect, 0.97
