The c.4213C>T (p.P1405S) alteration is located in exon 14 (coding exon 14) of the LMTK3 gene. This alteration results from a C to T substitution at nucleotide position 4213, causing the proline (P) at amino acid position 1405 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
