The c.1720G>C (p.V574L) alteration is located in exon 11 (coding exon 11) of the RETSAT gene. This alteration results from a G to C substitution at nucleotide position 1720, causing the valine (V) at amino acid position 574 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
