The c.2018G>A (p.R673H) 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 2018, causing the arginine (R) at amino acid position 673 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
