Genes affected

RRAGD (HGNC:19903): (Ras related GTP binding D) RRAGD is a monomeric guanine nucleotide-binding protein, or G protein. By binding GTP or GDP, small G proteins act as molecular switches in numerous cell processes and signaling pathways.[supplied by OMIM, Apr 2004]

RRAGD Gene-Disease associations (from GenCC):

hypomagnesemia 7, renal, with or without dilated cardiomyopathy

ACMG classification

Classification was made for transcript

Our verdict: Benign. The variant received -7 ACMG points.

PP2

Missense variant in the gene, where a lot of missense mutations are associated with disease in ClinVar. The gene has 6 curated pathogenic missense variants (we use a threshold of 10). The gene has 0 curated benign missense variants. Gene score misZ: 2.1976 (below the threshold of 3.09). Trascript score misZ: 2.3889 (below the threshold of 3.09). GenCC associations: The gene is linked to hypomagnesemia 7, renal, with or without dilated cardiomyopathy.

BP4

Computational evidence support a benign effect (MetaRNN=0.014571995).

BS2

High AC in GnomAd4 at 11 AD gene.
