The c.3925G>A (p.E1309K) alteration is located in exon 6 (coding exon 6) of the PLIN4 gene. This alteration results from a G to A substitution at nucleotide position 3925, causing the glutamic acid (E) at amino acid position 1309 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
