The c.3896C>A (p.A1299E) alteration is located in exon 13 (coding exon 13) of the LMTK3 gene. This alteration results from a C to A substitution at nucleotide position 3896, causing the alanine (A) at amino acid position 1299 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
