Genes affected
LILRA2 (HGNC:6603): (leukocyte immunoglobulin like receptor A2) This gene encodes a member of a family of immunoreceptors that are expressed predominantly on monocytes and B cells, and at lower levels on dendritic cells and natural killer cells. The encoded protein is an activating receptor that inhibits dendritic cell differentiation and antigen presentation and suppresses innate immune response. Alternatively spliced transcript variants encoding different isoforms have been found. This gene is located in a cluster of related genes on chromosome 19 and there is a pseudogene for this gene on chromosome 3. [provided by RefSeq, Mar 2014]

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 05, 2024The c.362G>T (p.S121I) alteration is located in exon 4 (coding exon 4) of the LILRA2 gene. This alteration results from a G to T substitution at nucleotide position 362, causing the serine (S) at amino acid position 121 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
