The c.1340C>T (p.P447L) alteration is located in exon 13 (coding exon 12) of the PATL2 gene. This alteration results from a C to T substitution at nucleotide position 1340, causing the proline (P) at amino acid position 447 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
