The c.442C>A (p.L148M) alteration is located in exon 5 (coding exon 4) of the PQLC2 gene. This alteration results from a C to A substitution at nucleotide position 442, causing the leucine (L) at amino acid position 148 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
