The c.1168G>C (p.E390Q) alteration is located in exon 12 (coding exon 12) of the ARFGAP2 gene. This alteration results from a G to C substitution at nucleotide position 1168, causing the glutamic acid (E) at amino acid position 390 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
