The c.343C>T (p.R115W) alteration is located in exon 4 (coding exon 3) of the RPL26L1 gene. This alteration results from a C to T substitution at nucleotide position 343, causing the arginine (R) at amino acid position 115 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
