Genes affected

GPC5 (HGNC:4453): (glypican 5) Cell surface heparan sulfate proteoglycans are composed of a membrane-associated protein core substituted with a variable number of heparan sulfate chains. Members of the glypican-related integral membrane proteoglycan family (GRIPS) contain a core protein anchored to the cytoplasmic membrane via a glycosyl phosphatidylinositol linkage. These proteins may play a role in the control of cell division and growth regulation. [provided by RefSeq, Jul 2008]

Ambry Genetics

Jan 23, 2023

The c.22G>T (p.V8L) alteration is located in exon 1 (coding exon 1) of the GPC5 gene. This alteration results from a G to T substitution at nucleotide position 22, causing the valine (V) at amino acid position 8 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
