Genes affected
SDC4 (HGNC:10661): (syndecan 4) The protein encoded by this gene is a transmembrane (type I) heparan sulfate proteoglycan that functions as a receptor in intracellular signaling. The encoded protein is found as a homodimer and is a member of the syndecan proteoglycan family. This gene is found on chromosome 20, while a pseudogene has been found on chromosome 22.

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJun 30, 2022The c.458G>C (p.G153A) alteration is located in exon 5 (coding exon 5) of the SDC4 gene. This alteration results from a G to C substitution at nucleotide position 458, causing the glycine (G) at amino acid position 153 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
