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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsApr 12, 2022The c.863G>A (p.R288H) alteration is located in exon 7 (coding exon 6) of the EPYC gene. This alteration results from a G to A substitution at nucleotide position 863, causing the arginine (R) at amino acid position 288 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
