The c.1340A>G (p.E447G) alteration is located in exon 10 (coding exon 10) of the MAP7D2 gene. This alteration results from a A to G substitution at nucleotide position 1340, causing the glutamic acid (E) at amino acid position 447 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
