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]

LOC105376576 (HGNC:):

ACMG classification

Our verdict: Likely_benign. The variant received -4 ACMG points.

• BP4: Computational evidence support a benign effect (MetaRNN=0.04955855).

Collection Method: clinical testing

The c.5C>A (p.T2K) alteration is located in exon 1 (coding exon 1) of the NCR3LG1 gene. This alteration results from a C to A substitution at nucleotide position 5, causing the threonine (T) at amino acid position 2 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
