Genes affected
GPC1 (HGNC:4449): (glypican 1) 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]

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsSep 17, 2021The c.298C>T (p.L100F) alteration is located in exon 2 (coding exon 2) of the GPC1 gene. This alteration results from a C to T substitution at nucleotide position 298, causing the leucine (L) at amino acid position 100 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
