The c.368T>C (p.L123P) alteration is located in exon 4 (coding exon 3) of the PLD4 gene. This alteration results from a T to C substitution at nucleotide position 368, causing the leucine (L) at amino acid position 123 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
