The c.1411C>A (p.L471M) alteration is located in exon 14 (coding exon 13) of the PATL2 gene. This alteration results from a C to A substitution at nucleotide position 1411, causing the leucine (L) at amino acid position 471 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
