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]

NKTR (HGNC:):

ACMG classification

Verdict is Uncertain_significance. Variant got 3 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• PP3: MetaRNN computational evidence supports a deleterious effect, 0.756

The c.341G>A (p.R114Q) alteration is located in exon 6 (coding exon 5) of the NKTR gene. This alteration results from a G to A substitution at nucleotide position 341, causing the arginine (R) at amino acid position 114 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
