The c.5258A>G (p.K1753R) alteration is located in exon 29 (coding exon 29) of the LTN1 gene. This alteration results from a A to G substitution at nucleotide position 5258, causing the lysine (K) at amino acid position 1753 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
