Genes affected

RHCG (HGNC:18140): (Rh family C glycoprotein) Enables ammonium transmembrane transporter activity; ankyrin binding activity; and identical protein binding activity. Involved in ammonium transmembrane transport; cellular ion homeostasis; and transepithelial ammonium transport. Located in apical plasma membrane and basolateral plasma membrane. Is integral component of plasma membrane. [provided by Alliance of Genome Resources, Apr 2022]

Collection Method: clinical testing

The c.1060G>A (p.V354M) alteration is located in exon 7 (coding exon 7) of the RHCG gene. This alteration results from a G to A substitution at nucleotide position 1060, causing the valine (V) at amino acid position 354 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
