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.822C>G (p.H274Q) alteration is located in exon 7 (coding exon 6) of the EPYC gene. This alteration results from a C to G substitution at nucleotide position 822, causing the histidine (H) at amino acid position 274 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
