The c.1783T>C (p.F595L) alteration is located in exon 7 (coding exon 6) of the SMYD4 gene. This alteration results from a T to C substitution at nucleotide position 1783, causing the phenylalanine (F) at amino acid position 595 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
