The c.3675C>A (p.D1225E) alteration is located in exon 12 (coding exon 12) of the LMTK3 gene. This alteration results from a C to A substitution at nucleotide position 3675, causing the aspartic acid (D) at amino acid position 1225 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
