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]

Collection Method: clinical testing

The c.88G>C (p.E30Q) alteration is located in exon 1 (coding exon 1) of the AGAP6 gene. This alteration results from a G to C substitution at nucleotide position 88, causing the glutamic acid (E) at amino acid position 30 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
