Genes affected

PILRB (HGNC:18297): (paired immunoglobin like type 2 receptor beta) The paired immunoglobin-like type 2 receptors consist of highly related activating and inhibitory receptors that are involved in the regulation of many aspects of the immune system. The paired immunoglobulin-like receptor genes are located in a tandem head-to-tail orientation on chromosome 7. This gene encodes the activating member of the receptor pair and contains a truncated cytoplasmic tail relative to its inhibitory counterpart (PILRA), that has a long cytoplasmic tail with immunoreceptor tyrosine-based inhibitory (ITIM) motifs. This gene is thought to have arisen from a duplication of the inhibitory PILRA gene and evolved to acquire its activating function. [provided by RefSeq, Jun 2013]

The c.346C>G (p.R116G) alteration is located in exon 2 (coding exon 2) of the PILRB gene. This alteration results from a C to G substitution at nucleotide position 346, causing the arginine (R) at amino acid position 116 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
