Ambry Genetics

Jul 05, 2023

The c.32C>G (p.S11C) alteration is located in exon 2 (coding exon 1) of the LRRC8C gene. This alteration results from a C to G substitution at nucleotide position 32, causing the serine (S) at amino acid position 11 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
