The c.704A>G (p.H235R) alteration is located in exon 7 (coding exon 7) of the PLPP4 gene. This alteration results from a A to G substitution at nucleotide position 704, causing the histidine (H) at amino acid position 235 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
