The c.37A>G (p.T13A) alteration is located in exon 2 (coding exon 2) of the RPL22L1 gene. This alteration results from a A to G substitution at nucleotide position 37, causing the threonine (T) at amino acid position 13 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
