The c.835G>T (p.D279Y) alteration is located in exon 8 (coding exon 6) of the ECT2L gene. This alteration results from a G to T substitution at nucleotide position 835, causing the aspartic acid (D) at amino acid position 279 to be replaced by a tyrosine (Y). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
