The c.4697A>G (p.E1566G) alteration is located in exon 40 (coding exon 40) of the PSME4 gene. This alteration results from a A to G substitution at nucleotide position 4697, causing the glutamic acid (E) at amino acid position 1566 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
