Genes affected
IL31 (HGNC:19372): (interleukin 31) IL31, which is made principally by activated Th2-type T cells, interacts with a heterodimeric receptor consisting of IL31RA (MIM 609510) and OSMR (MIM 601743) that is constitutively expressed on epithelial cells and keratinocytes. IL31 may be involved in the promotion of allergic skin disorders and in regulating other allergic diseases, such as asthma (Dillon et al., 2004 [PubMed 15184896]).[supplied by OMIM, Mar 2008]
LRRC43 (HGNC:28562): (leucine rich repeat containing 43)

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 13, 2021The c.297C>A (p.D99E) alteration is located in exon 3 (coding exon 3) of the IL31 gene. This alteration results from a C to A substitution at nucleotide position 297, causing the aspartic acid (D) at amino acid position 99 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
