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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMar 21, 2022The c.1061C>T (p.A354V) 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 1061, causing the alanine (A) at amino acid position 354 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
