Variant summary

Our verdict is Likely benign. Variant got -2 ACMG points: 2P and 4B. PM2 BP4_Strong

The NM_001077665.3(AGAP6):​c.706A>C​(p.Thr236Pro) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant was absent in control chromosomes in GnomAD project. In-silico tool predicts a benign outcome for this variant. 13/18 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. T236A) has been classified as Uncertain significance.

• Frequency: Genomes: not found (cov: 30)
• Consequence: AGAP6 NM_001077665.3 missense
• Clinical Significance: Not reported in ClinVar
• Conservation: PhyloP100: 0.253

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

Verdict is Likely_benign. Variant got -2 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (MetaRNN=0.061411977).
