Ambry Genetics

Feb 10, 2022

The c.241G>C (p.E81Q) alteration is located in exon 2 (coding exon 2) of the ZCCHC4 gene. This alteration results from a G to C substitution at nucleotide position 241, causing the glutamic acid (E) at amino acid position 81 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
