The c.3868C>T (p.R1290W) alteration is located in exon 6 (coding exon 6) of the PLIN4 gene. This alteration results from a C to T substitution at nucleotide position 3868, causing the arginine (R) at amino acid position 1290 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
