The c.1398C>A (p.H466Q) alteration is located in exon 13 (coding exon 13) of the PEX5L gene. This alteration results from a C to A substitution at nucleotide position 1398, causing the histidine (H) at amino acid position 466 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
