The c.349C>T (p.R117W) alteration is located in exon 3 (coding exon 3) of the LEXM gene. This alteration results from a C to T substitution at nucleotide position 349, causing the arginine (R) at amino acid position 117 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
