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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsNov 24, 2024The c.378C>G (p.F126L) alteration is located in exon 3 (coding exon 3) of the GPC1 gene. This alteration results from a C to G substitution at nucleotide position 378, causing the phenylalanine (F) at amino acid position 126 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
