Genes affected

SDC3 (HGNC:10660): (syndecan 3) The protein encoded by this gene belongs to the syndecan proteoglycan family. It may play a role in the organization of cell shape by affecting the actin cytoskeleton, possibly by transferring signals from the cell surface in a sugar-dependent mechanism. Allelic variants of this gene have been associated with obesity. [provided by RefSeq, Oct 2009]

Ambry Genetics

Jan 26, 2022

The c.968A>C (p.E323A) alteration is located in exon 4 (coding exon 4) of the SDC3 gene. This alteration results from a A to C substitution at nucleotide position 968, causing the glutamic acid (E) at amino acid position 323 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
