Genes affected

CD96 (HGNC:16892): (CD96 molecule) The protein encoded by this gene belongs to the immunoglobulin superfamily. It is a type I membrane protein. The protein may play a role in the adhesive interactions of activated T and NK cells during the late phase of the immune response. It may also function in antigen presentation. Alternative splicing generates multiple transcript variants encoding distinct isoforms. [provided by RefSeq, Jan 2016]

ACMG classification

Verdict is Benign. Variant got -8 ACMG points.

• BP4: Computational evidence support a benign effect (MetaRNN=0.054051787).
• BS2: High AC in GnomAd at 8 AD gene.

Ambry Genetics

Nov 13, 2023

The c.199C>A (p.L67M) alteration is located in exon 2 (coding exon 2) of the CD96 gene. This alteration results from a C to A substitution at nucleotide position 199, causing the leucine (L) at amino acid position 67 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
