The c.697A>G (p.T233A) 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 697, causing the threonine (T) at amino acid position 233 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
