• NM_006570.5:c.922_924delCACinsTAT
• RRAGA p.His308Tyr

Variant summary

Our verdict is Uncertain significance. The variant received 1 ACMG points: 1P and 0B. PP3

The NM_006570.5(RRAGA):​c.922_924delCACinsTAT​(p.His308Tyr) variant causes a missense change involving the alteration of a conserved nucleotide. The variant was absent in control chromosomes in GnomAD project. It is difficult to determine the true allele frequency of this variant because it is of type MNV, and the frequency of such variant types in population databases may be underestimated and unreliable. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar. Another nucleotide change resulting in the same amino acid substitution has been previously reported as Uncertain significance in ClinVar.

Genes affected

RRAGA (HGNC:16963): (Ras related GTP binding A) Enables several functions, including GTP binding activity; protein dimerization activity; and ubiquitin protein ligase binding activity. Involved in several processes, including cellular response to amino acid starvation; negative regulation of autophagy; and positive regulation of TORC1 signaling. Located in lysosome and nucleus. Colocalizes with GATOR1 complex. [provided by Alliance of Genome Resources, Apr 2022]
