Position:

• chr1-240870094-C-G

Variant summary

Our verdict is Uncertain significance. Variant got 1 ACMG points: 2P and 1B. PM2 BP4

The NM_001364886.1(RGS7):​c.411G>C​(p.Met137Ile) 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 benign outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. M137L) has been classified as Likely benign.

• Frequency: Genomes: not found (cov: 32)
• Consequence: RGS7 NM_001364886.1 missense
• Clinical Significance: Uncertain significance criteria provided, single submitter U:1
• Conservation: PhyloP100: 7.79

Genes affected

RGS7 (HGNC:10003): (regulator of G protein signaling 7) Enables G-protein beta-subunit binding activity and GTPase activator activity. Involved in positive regulation of GTPase activity. Located in cytosol. [provided by Alliance of Genome Resources, Apr 2022]

ACMG classification

Verdict is Uncertain_significance. Variant got 1 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (MetaRNN=0.41967767).

The c.411G>C (p.M137I) alteration is located in exon 7 (coding exon 6) of the RGS7 gene. This alteration results from a G to C substitution at nucleotide position 411, causing the methionine (M) at amino acid position 137 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
