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]

Sep 25, 2023

The c.859C>T (p.L287F) alteration is located in exon 6 (coding exon 6) of the RHCG gene. This alteration results from a C to T substitution at nucleotide position 859, causing the leucine (L) at amino acid position 287 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
