The c.350A>G (p.E117G) alteration is located in exon 7 (coding exon 1) of the HNRNPA1L2 gene. This alteration results from a A to G substitution at nucleotide position 350, causing the glutamic acid (E) at amino acid position 117 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
