The c.1771T>C (p.S591P) 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 1771, causing the serine (S) at amino acid position 591 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
