The c.1414G>C (p.E472Q) alteration is located in exon 9 (coding exon 9) of the RETSAT gene. This alteration results from a G to C substitution at nucleotide position 1414, causing the glutamic acid (E) at amino acid position 472 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
