Genes affected

ULBP2 (HGNC:14894): (UL16 binding protein 2) This gene encodes a major histocompatibility complex (MHC) class I-related molecule that binds to the NKG2D receptor on natural killer (NK) cells to trigger release of multiple cytokines and chemokines that in turn contribute to the recruitment and activation of NK cells. The encoded protein undergoes further processing to generate the mature protein that is either anchored to membrane via a glycosylphosphatidylinositol moiety, or secreted. Many malignant cells secrete the encoded protein to evade immunosurveillance by NK cells. This gene is located in a cluster of multiple MHC class I-related genes on chromosome 6.

The c.101G>A (p.C34Y) alteration is located in exon 2 (coding exon 2) of the ULBP2 gene. This alteration results from a G to A substitution at nucleotide position 101, causing the cysteine (C) at amino acid position 34 to be replaced by a tyrosine (Y). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
