The c.691C>G (p.R231G) alteration is located in exon 8 (coding exon 7) of the ARHGAP28 gene. This alteration results from a C to G substitution at nucleotide position 691, causing the arginine (R) at amino acid position 231 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
