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]

Dec 07, 2021

The c.1067C>T (p.P356L) alteration is located in exon 4 (coding exon 4) of the SDC3 gene. This alteration results from a C to T substitution at nucleotide position 1067, causing the proline (P) at amino acid position 356 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
