The c.2038G>A (p.G680R) alteration is located in exon 14 (coding exon 14) of the MROH6 gene. This alteration results from a G to A substitution at nucleotide position 2038, causing the glycine (G) at amino acid position 680 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
