The c.299A>T (p.Q100L) alteration is located in exon 5 (coding exon 4) of the PAPLN gene. This alteration results from a A to T substitution at nucleotide position 299, causing the glutamine (Q) at amino acid position 100 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
