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]

Ambry Genetics

Nov 22, 2021

The c.852G>C (p.L284F) alteration is located in exon 7 (coding exon 6) of the EPYC gene. This alteration results from a G to C substitution at nucleotide position 852, causing the leucine (L) at amino acid position 284 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
