Ambry Genetics

Apr 25, 2022

The c.784G>C (p.E262Q) alteration is located in exon 3 (coding exon 3) of the ALKBH4 gene. This alteration results from a G to C substitution at nucleotide position 784, causing the glutamic acid (E) at amino acid position 262 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
