Ambry Genetics

Nov 14, 2023

The c.214G>C (p.E72Q) alteration is located in exon 3 (coding exon 3) of the RTFDC1 gene. This alteration results from a G to C substitution at nucleotide position 214, causing the glutamic acid (E) at amino acid position 72 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
