Dec 14, 2023

The c.789C>G (p.C263W) alteration is located in exon 8 (coding exon 6) of the LRRC39 gene. This alteration results from a C to G substitution at nucleotide position 789, causing the cysteine (C) at amino acid position 263 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
