The c.693G>C (p.R231S) alteration is located in exon 7 (coding exon 5) of the ECT2L gene. This alteration results from a G to C substitution at nucleotide position 693, causing the arginine (R) at amino acid position 231 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
