Variant summary

Our verdict is Uncertain significance. The variant received 0 ACMG points: 2P and 2B. PM2 BP4_Moderate

The NM_001077665.3(AGAP6):​c.410G>C​(p.Arg137Pro) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.000000685 in 1,460,544 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 15/20 in silico tools predict a benign 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. R137H) has been classified as Likely benign.

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]

ACMG classification

Our verdict: Uncertain_significance. The variant received 0 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (MetaRNN=0.14285222).
