The c.188G>A (p.S63N) alteration is located in exon 4 (coding exon 3) of the PAPLN gene. This alteration results from a G to A substitution at nucleotide position 188, causing the serine (S) at amino acid position 63 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
