The c.3787C>T (p.L1263F) 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 3787, causing the leucine (L) at amino acid position 1263 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
