Genes affected

EPYC (HGNC:3053): (epiphycan) Dermatan sulfate proteoglycan 3 is a member of the small leucine-rich repeat proteoglycan family. This gene is composed of seven exons. It regulates fibrillogenesis by interacting with collagen fibrils and other extracellular matrix proteins. [provided by RefSeq, Jul 2008]

The c.652A>G (p.I218V) alteration is located in exon 5 (coding exon 4) of the EPYC gene. This alteration results from a A to G substitution at nucleotide position 652, causing the isoleucine (I) at amino acid position 218 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
