The c.347A>G (p.D116G) alteration is located in exon 4 (coding exon 4) of the RPL22L1 gene. This alteration results from a A to G substitution at nucleotide position 347, causing the aspartic acid (D) at amino acid position 116 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
