The c.3814T>C (p.F1272L) alteration is located in exon 13 (coding exon 13) of the LMTK3 gene. This alteration results from a T to C substitution at nucleotide position 3814, causing the phenylalanine (F) at amino acid position 1272 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
