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.

The c.1222A>T (p.T408S) alteration is located in exon 7 (coding exon 7) of the IL20RA gene. This alteration results from a A to T substitution at nucleotide position 1222, causing the threonine (T) at amino acid position 408 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
