The c.189G>T (p.W63C) alteration is located in exon 2 (coding exon 1) of the LSM10 gene. This alteration results from a G to T substitution at nucleotide position 189, causing the tryptophan (W) at amino acid position 63 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
