Variant summary

Our verdict is Uncertain significance. Variant got 3 ACMG points: 3P and 0B. PM2 PP3

The NM_020407.5(RHBG):​c.428T>C​(p.Val143Ala) variant causes a missense change involving the alteration of a conserved nucleotide. The variant was absent in control chromosomes in GnomAD project. In-silico tool predicts a pathogenic outcome for this variant. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar. Another variant affecting the same amino acid position, but resulting in a different missense (i.e. V143D) has been classified as Likely benign.

• Frequency: Genomes: not found (cov: 31)
• Consequence: RHBG NM_020407.5 missense
• Clinical Significance: Not reported in ClinVar
• Conservation: PhyloP100: 7.89

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]

RHBG (HGNC:):

ACMG classification
