The c.3367C>T (p.L1123F) alteration is located in exon 29 (coding exon 29) of the ATP13A4 gene. This alteration results from a C to T substitution at nucleotide position 3367, causing the leucine (L) at amino acid position 1123 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
