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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 21, 2023The c.1265G>T (p.G422V) alteration is located in exon 9 (coding exon 9) of the RHCG gene. This alteration results from a G to T substitution at nucleotide position 1265, causing the glycine (G) at amino acid position 422 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
