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]

DCBLD2 links:

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.

Ambry Genetics

Jul 14, 2021

The c.1111A>G (p.M371V) alteration is located in exon 9 (coding exon 9) of the DCBLD2 gene. This alteration results from a A to G substitution at nucleotide position 1111, causing the methionine (M) at amino acid position 371 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
