The c.484C>G (p.H162D) alteration is located in exon 4 (coding exon 4) of the PSMA8 gene. This alteration results from a C to G substitution at nucleotide position 484, causing the histidine (H) at amino acid position 162 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
