Jan 12, 2024

The c.1018G>A (p.D340N) alteration is located in exon 3 (coding exon 1) of the MROH7 gene. This alteration results from a G to A substitution at nucleotide position 1018, causing the aspartic acid (D) at amino acid position 340 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
