Genes affected

GC (HGNC:4187): (GC vitamin D binding protein) The protein encoded by this gene belongs to the albumin gene family. It is a multifunctional protein found in plasma, ascitic fluid, cerebrospinal fluid and on the surface of many cell types. It binds to vitamin D and its plasma metabolites and transports them to target tissues. Alternatively spliced transcript variants encoding different isoforms have been found for this gene.[provided by RefSeq, Feb 2011]

Ambry Genetics

Jul 26, 2022

The c.653G>A (p.R218K) alteration is located in exon 6 (coding exon 6) of the GC gene. This alteration results from a G to A substitution at nucleotide position 653, causing the arginine (R) at amino acid position 218 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
