The c.803A>G (p.E268G) alteration is located in exon 7 (coding exon 6) of the ARHGEF37 gene. This alteration results from a A to G substitution at nucleotide position 803, causing the glutamic acid (E) at amino acid position 268 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
