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]

The c.645G>A (p.M215I) alteration is located in exon 3 (coding exon 3) of the GPC5 gene. This alteration results from a G to A substitution at nucleotide position 645, causing the methionine (M) at amino acid position 215 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
