Genes affected

DCBLD2 (HGNC:24627): (discoidin, CUB and LCCL domain containing 2) Involved in negative regulation of cell growth and wound healing. Located in cell surface. Is integral component of plasma membrane. [provided by Alliance of Genome Resources, Apr 2022]

ST3GAL6 (HGNC:18080): (ST3 beta-galactoside alpha-2,3-sialyltransferase 6) The protein encoded by this gene is a member of the sialyltransferase family. Members of this family are enzymes that transfer sialic acid from the activated cytidine 5'-monophospho-N-acetylneuraminic acid to terminal positions on sialylated glycolipids (gangliosides) or to the N- or O-linked sugar chains of glycoproteins. This protein has high specificity for neolactotetraosylceramide and neolactohexaosylceramide as glycolipid substrates and may contribute to the formation of selectin ligands and sialyl Lewis X, a carbohydrate important for cell-to-cell recognition and a blood group antigen.

ACMG classification

Our verdict: Benign. The variant received -12 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.78).
• BA1: GnomAd4 highest subpopulation (EAS) allele frequency at 95% confidence interval = 0.682 is higher than 0.05.
