GPC6
protein-codingglypican 6, the group of Glypicans
Gene summary
The glypicans comprise a family of glycosylphosphatidylinositol-anchored heparan sulfate proteoglycans, and they have been implicated in the control of cell growth and cell division. The glypican encoded by this gene is a putative cell surface coreceptor for growth factors, extracellular matrix proteins, proteases and anti-proteases. Mutations in this gene are associated with omodysplasia 1. [provided by RefSeq, Nov 2016]

ClinVar Variants & Pathogenicity by Type
Statistics based on transcript NM_005708.5. Only rare variants are included.
We include only reliable ClinVar variants with their consequences to MANE Select, MANE Plus Clinical transcripts, or transcripts with TSL equal to 1. Click a count to filter the variants table below.
Slight differences between displayed counts and ClinVar may occur due to a different transcript/consequence chosen by our variant effect predictor, or because we classify Benign/Likely benign as Likely benign and Pathogenic/Likely pathogenic as Likely pathogenic.

- Function
- FUNCTION: Cell surface proteoglycan that bears heparan sulfate. Putative cell surface coreceptor for growth factors, extracellular matrix proteins, proteases and anti-proteases (By similarity). Enhances migration and invasion of cancer cells through WNT5A signaling. {ECO:0000250, ECO:0000269|PubMed:21871017}.;
- Disease
- DISEASE: Omodysplasia 1 (OMOD1) [MIM:258315]: A rare autosomal recessive skeletal dysplasia characterized by facial dysmorphism and severe congenital micromelia with shortening and distal tapering of the humeri and femora, to give a club-like appearance. Typical facial features include a prominent forehead, frontal bossing, short nose with a depressed broad bridge, short columella, anteverted nostrils, long philtrum, and small chin. {ECO:0000269|PubMed:19481194}. Note=The disease is caused by mutations affecting the gene represented in this entry. Point mutations leading to protein truncation, as well as larger genomic rearrangements resulting in exon deletions, have been found in family segregating omodysplasia type 1. All mutations identified in individuals affected by omodysplasia could lead to the absence of a functional protein, the mutant RNAs being suspected to be nonsense-mediated mRNA decay (NMD) targets. Even if the mRNA escapes NMD and is translated, all mutations are expected to disrupt the three-dimensional protein structure and often to abolish multiple highly conserved cysteine residues.;
