Nov 10, 2022

The c.887G>A (p.R296Q) alteration is located in exon 8 (coding exon 6) of the ECT2L gene. This alteration results from a G to A substitution at nucleotide position 887, causing the arginine (R) at amino acid position 296 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
