The c.1732C>A (p.Q578K) alteration is located in exon 11 (coding exon 11) of the RETSAT gene. This alteration results from a C to A substitution at nucleotide position 1732, causing the glutamine (Q) at amino acid position 578 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
