The c.34C>A (p.P12T) alteration is located in exon 3 (coding exon 1) of the LETM2 gene. This alteration results from a C to A substitution at nucleotide position 34, causing the proline (P) at amino acid position 12 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
