Genes affected

LYVE1 (HGNC:14687): (lymphatic vessel endothelial hyaluronan receptor 1) This gene encodes a type I integral membrane glycoprotein. The encoded protein acts as a receptor and binds to both soluble and immobilized hyaluronan. This protein may function in lymphatic hyaluronan transport and have a role in tumor metastasis.

IRAG1-AS1 (HGNC:43434): (IRAG1 antisense RNA 1)

ACMG classification

Verdict is Uncertain_significance. Variant got 2 ACMG points.

• PM2: Very rare variant in population databases, with high coverage

Collection Method: clinical testing

The c.275A>G (p.D92G) alteration is located in exon 3 (coding exon 3) of the LYVE1 gene. This alteration results from a A to G substitution at nucleotide position 275, causing the aspartic acid (D) at amino acid position 92 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
