The c.711G>A (p.M237I) alteration is located in exon 6 (coding exon 6) of the ARHGEF38 gene. This alteration results from a G to A substitution at nucleotide position 711, causing the methionine (M) at amino acid position 237 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
