The c.1768C>T (p.R590W) alteration is located in exon 11 (coding exon 11) of the RETSAT gene. This alteration results from a C to T substitution at nucleotide position 1768, causing the arginine (R) at amino acid position 590 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
