The c.1582G>A (p.V528M) alteration is located in exon 14 (coding exon 14) of the PEX5L gene. This alteration results from a G to A substitution at nucleotide position 1582, causing the valine (V) at amino acid position 528 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
