The c.1709A>G (p.N570S) alteration is located in exon 3 (coding exon 1) of the LRRC8D gene. This alteration results from a A to G substitution at nucleotide position 1709, causing the asparagine (N) at amino acid position 570 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
