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

Sep 14, 2022

The c.902T>C (p.I301T) alteration is located in exon 7 (coding exon 6) of the EPYC gene. This alteration results from a T to C substitution at nucleotide position 902, causing the isoleucine (I) at amino acid position 301 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
