Genes affected

SDCBP (HGNC:10662): (syndecan binding protein) The protein encoded by this gene was initially identified as a molecule linking syndecan-mediated signaling to the cytoskeleton. The syntenin protein contains tandemly repeated PDZ domains that bind the cytoplasmic, C-terminal domains of a variety of transmembrane proteins. This protein may also affect cytoskeletal-membrane organization, cell adhesion, protein trafficking, and the activation of transcription factors. The protein is primarily localized to membrane-associated adherens junctions and focal adhesions but is also found at the endoplasmic reticulum and nucleus. Alternative splicing results in multiple transcript variants encoding different isoforms. Related pseudogenes have been identified on multiple chromosomes. [provided by RefSeq, Jan 2017]

Ambry Genetics

Dec 13, 2023

The c.362A>G (p.Q121R) alteration is located in exon 5 (coding exon 4) of the SDCBP gene. This alteration results from a A to G substitution at nucleotide position 362, causing the glutamine (Q) at amino acid position 121 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
