• AGAP6 p.Gly35Arg

Variant summary

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

The NM_001077665.3(AGAP6):​c.103_105delGGAinsCGG​(p.Gly35Arg) variant causes a missense change involving the alteration of a non-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

AGAP6 (HGNC:23466): (ArfGAP with GTPase domain, ankyrin repeat and PH domain 6) Predicted to enable GTPase activator activity and metal ion binding activity. Predicted to be involved in regulation of catalytic activity. Predicted to be active in nucleus. [provided by Alliance of Genome Resources, Apr 2022]

TIMM23B-AGAP6 (HGNC:45009): (TIMM23B-AGAP6 readthrough (NMD candidate)) This locus represents naturally-occurring readthrough transcription between the adjacent TIMM23B (translocase of inner mitochondrial membrane 23 homolog B) and AGAP6 (ArfGAP with GTPase domain, ankyrin repeat and PH domain 6) genes. Readthrough transcripts contain portions of the coding sequence for both genes and are predicted to be candidates for nonsense-mediated decay (NMD). [provided by RefSeq, Sep 2018]
