Dec 14, 2021

The c.1108A>G (p.N370D) alteration is located in exon 10 (coding exon 10) of the MEP1A gene. This alteration results from a A to G substitution at nucleotide position 1108, causing the asparagine (N) at amino acid position 370 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
