Genes affected

RHBG (HGNC:14572): (Rh family B glycoprotein) This gene encodes one of two non-erythroid members of the Rhesus (Rh) protein family. Non-erythroid Rh protein family members are mainly expressed in the kidney and belong to the methylammonium-ammonium permease/ammonia transporters superfamily. All Rh family proteins are predicted to be transmembrane proteins with 12 membrane spanning domains and intracytoplasmic N- and C-termini. Alternative splicing of this gene results in multiple transcript variants. [provided by RefSeq, Jan 2012]

The c.977C>T (p.T326M) alteration is located in exon 6 (coding exon 6) of the RHBG gene. This alteration results from a C to T substitution at nucleotide position 977, causing the threonine (T) at amino acid position 326 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
