Genes affected

LGALS2 (HGNC:6562): (galectin 2) The protein encoded by this gene is a soluble beta-galactoside binding lectin. The encoded protein is found as a homodimer and can bind to lymphotoxin-alpha. A single nucleotide polymorphism in an intron of this gene can alter the transcriptional level of the protein, with a resultant increased risk of myocardial infarction.

ACMG classification

Verdict is Uncertain_significance. Variant got 0 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (MetaRNN=0.100601256).

The c.301C>T (p.H101Y) alteration is located in exon 4 (coding exon 4) of the LGALS2 gene. This alteration results from a C to T substitution at nucleotide position 301, causing the histidine (H) at amino acid position 101 to be replaced by a tyrosine (Y). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
