The c.5393T>G (p.I1798S) alteration is located in exon 45 (coding exon 45) of the PSME4 gene. This alteration results from a T to G substitution at nucleotide position 5393, causing the isoleucine (I) at amino acid position 1798 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
