The c.3991A>G (p.M1331V) alteration is located in exon 20 (coding exon 20) of the PXDNL gene. This alteration results from a A to G substitution at nucleotide position 3991, causing the methionine (M) at amino acid position 1331 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
