Genes affected

NKTR (HGNC:7833): (natural killer cell triggering receptor) This gene encodes a membrane-anchored protein with a hydrophobic amino terminal domain and a cyclophilin-like PPIase domain. It is present on the surface of natural killer cells and facilitates their binding to targets. Its expression is regulated by IL2 activation of the cells. [provided by RefSeq, Jul 2008]

The c.914C>T (p.T305I) alteration is located in exon 10 (coding exon 9) of the NKTR gene. This alteration results from a C to T substitution at nucleotide position 914, causing the threonine (T) at amino acid position 305 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
