Genes affected

GYPC (HGNC:4704): (glycophorin C (Gerbich blood group)) Glycophorin C (GYPC) is an integral membrane glycoprotein. It is a minor species carried by human erythrocytes, but plays an important role in regulating the mechanical stability of red cells. A number of glycophorin C mutations have been described. The Gerbich and Yus phenotypes are due to deletion of exon 3 and 2, respectively. The Webb and Duch antigens, also known as glycophorin D, result from single point mutations of the glycophorin C gene. The glycophorin C protein has very little homology with glycophorins A and B. Alternate splicing results in multiple transcript variants. [provided by RefSeq, Feb 2012]

Ambry Genetics

Jun 27, 2022

The c.172G>A (p.D58N) alteration is located in exon 3 (coding exon 3) of the GYPC gene. This alteration results from a G to A substitution at nucleotide position 172, causing the aspartic acid (D) at amino acid position 58 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
