Genes affected

SDC2 (HGNC:10659): (syndecan 2) The protein encoded by this gene is a transmembrane (type I) heparan sulfate proteoglycan and is a member of the syndecan proteoglycan family. The syndecans mediate cell binding, cell signaling, and cytoskeletal organization and syndecan receptors are required for internalization of the HIV-1 tat protein. The syndecan-2 protein functions as an integral membrane protein and participates in cell proliferation, cell migration and cell-matrix interactions via its receptor for extracellular matrix proteins. Altered syndecan-2 expression has been detected in several different tumor types. [provided by RefSeq, Jul 2008]

Ambry Genetics

Jan 26, 2023

The c.89T>A (p.M30K) alteration is located in exon 2 (coding exon 2) of the SDC2 gene. This alteration results from a T to A substitution at nucleotide position 89, causing the methionine (M) at amino acid position 30 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
