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 GeneticsNov 09, 2024The c.890C>G (p.A297G) alteration is located in exon 6 (coding exon 6) of the RHCG gene. This alteration results from a C to G substitution at nucleotide position 890, causing the alanine (A) at amino acid position 297 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
