Ambry Genetics

May 27, 2022

The c.223G>A (p.V75I) alteration is located in exon 3 (coding exon 1) of the LRRC8D gene. This alteration results from a G to A substitution at nucleotide position 223, causing the valine (V) at amino acid position 75 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
