Collection Method: clinical testing

The c.458T>C (p.L153P) alteration is located in exon 4 (coding exon 4) of the ATP6AP1L gene. This alteration results from a T to C substitution at nucleotide position 458, causing the leucine (L) at amino acid position 153 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
