The c.500A>G (p.H167R) alteration is located in exon 5 (coding exon 5) of the FOPNL gene. This alteration results from a A to G substitution at nucleotide position 500, causing the histidine (H) at amino acid position 167 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
