The c.1300G>A (p.E434K) alteration is located in exon 5 (coding exon 2) of the L1TD1 gene. This alteration results from a G to A substitution at nucleotide position 1300, causing the glutamic acid (E) at amino acid position 434 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
