Genes affected

LAG3 (HGNC:6476): (lymphocyte activating 3) Lymphocyte-activation protein 3 belongs to Ig superfamily and contains 4 extracellular Ig-like domains. The LAG3 gene contains 8 exons. The sequence data, exon/intron organization, and chromosomal localization all indicate a close relationship of LAG3 to CD4. [provided by RefSeq, Jul 2008]

The c.628C>G (p.R210G) alteration is located in exon 4 (coding exon 4) of the LAG3 gene. This alteration results from a C to G substitution at nucleotide position 628, causing the arginine (R) at amino acid position 210 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
