Genes affected

LGALS12 (HGNC:15788): (galectin 12) This gene encodes a member of the galectin superfamily, a group of beta-galactoside-binding proteins with conserved carbohydrate recognition domains. The related mouse protein is a primary regulator of the early stages of adipose tissue development. Alternatively spliced transcript variants encoding different isoforms have been described.

ACMG classification

Verdict is Uncertain_significance. Variant got 1 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (MetaRNN=0.4021221).

The c.805C>T (p.R269C) alteration is located in exon 8 (coding exon 8) of the LGALS12 gene. This alteration results from a C to T substitution at nucleotide position 805, causing the arginine (R) at amino acid position 269 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
