The c.812A>G (p.N271S) alteration is located in exon 8 (coding exon 6) of the ECT2L gene. This alteration results from a A to G substitution at nucleotide position 812, causing the asparagine (N) at amino acid position 271 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
