RHCG

protein-coding

Rh family C glycoprotein, the group of Solute carrier family 42

Gene summary

Enables ankyrin binding activity; identical protein binding activity; and transmembrane transporter activity. Involved in ammonium transmembrane transport; intracellular monoatomic ion homeostasis; and transepithelial ammonium transport. Located in apical plasma membrane and basolateral plasma membrane.

ClinVar Variants & Pathogenicity by Type

Statistics based on transcript NM_016321.3. Only rare variants are included.

We include only reliable ClinVar variants with their consequences to MANE Select, MANE Plus Clinical transcripts, or transcripts with TSL equal to 1. Click a count to filter the variants table below.

Slight differences between displayed counts and ClinVar may occur due to a different transcript/consequence chosen by our variant effect predictor, or because we classify Benign/Likely benign as Likely benign and Pathogenic/Likely pathogenic as Likely pathogenic.
