Genes affected
IL20RA (HGNC:6003): (interleukin 20 receptor subunit alpha) This gene encodes a member of the type II cytokine receptor family. The encoded protein is a subunit of the receptor for interleukin 20, a cytokine that may be involved in epidermal function. The interleukin 20 receptor is a heterodimeric complex consisting of the encoded protein and interleukin 20 receptor beta. This gene and interleukin 20 receptor beta are highly expressed in skin, and are upregulated in psoriasis. Alternative splicing results in multiple transcript variants.

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsFeb 07, 2023The c.1498G>A (p.D500N) alteration is located in exon 7 (coding exon 7) of the IL20RA gene. This alteration results from a G to A substitution at nucleotide position 1498, causing the aspartic acid (D) at amino acid position 500 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
