The c.1943G>C (p.C648S) alteration is located in exon 3 (coding exon 2) of the LRRC32 gene. This alteration results from a G to C substitution at nucleotide position 1943, causing the cysteine (C) at amino acid position 648 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
