The c.242T>G (p.L81W) alteration is located in exon 3 (coding exon 3) of the RPL7L1 gene. This alteration results from a T to G substitution at nucleotide position 242, causing the leucine (L) at amino acid position 81 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
