Genes affected

IL31RA (HGNC:18969): (interleukin 31 receptor A) The protein encoded by this gene belongs to the type I cytokine receptor family. This receptor, with homology to gp130, is expressed on monocytes, and is involved in IL-31 signaling via activation of STAT-3 and STAT-5. It functions either as a monomer, or as part of a receptor complex with oncostatin M receptor (OSMR). Several alternatively spliced transcript variants encoding different isoforms have been noted for this gene.[provided by RefSeq, Jun 2011]

IL31RA Gene-Disease associations (from GenCC):

• familial primary localized cutaneous amyloidosis

  Inheritance: AD Classification: SUPPORTIVE Submitted by: Orphanet
• amyloidosis, primary localized cutaneous, 2

  Inheritance: Unknown, AD Classification: LIMITED Submitted by: Labcorp Genetics (formerly Invitae), Ambry Genetics

ACMG classification

Our verdict: Benign. The variant received -12 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.94).
• BA1: GnomAd4 highest subpopulation (AFR) allele frequency at 95% confidence interval = 0.822 is higher than 0.05.
