The c.1555T>C (p.F519L) alteration is located in exon 1 (coding exon 1) of the FAT3 gene. This alteration results from a T to C substitution at nucleotide position 1555, causing the phenylalanine (F) at amino acid position 519 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
