The c.539C>T (p.P180L) alteration is located in exon 6 (coding exon 6) of the ADHFE1 gene. This alteration results from a C to T substitution at nucleotide position 539, causing the proline (P) at amino acid position 180 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
