The c.4037C>A (p.P1346H) alteration is located in exon 22 (coding exon 22) of the LTN1 gene. This alteration results from a C to A substitution at nucleotide position 4037, causing the proline (P) at amino acid position 1346 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
