Genes affected

NCR3LG1 (HGNC:42400): (natural killer cell cytotoxicity receptor 3 ligand 1) B7H6 belongs to the B7 family (see MIM 605402) and is selectively expressed on tumor cells. Interaction of B7H6 with NKp30 (NCR3; MIM 611550) results in natural killer (NK) cell activation and cytotoxicity (Brandt et al., 2009 [PubMed 19528259]).[supplied by OMIM, Jan 2011]

ACMG classification

Verdict is Likely_benign. Variant got -2 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (MetaRNN=0.051120043).

The c.289C>A (p.P97T) alteration is located in exon 2 (coding exon 2) of the NCR3LG1 gene. This alteration results from a C to A substitution at nucleotide position 289, causing the proline (P) at amino acid position 97 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
