Mar 18, 2024

The c.446A>G (p.E149G) alteration is located in exon 2 (coding exon 2) of the TRIM49B gene. This alteration results from a A to G substitution at nucleotide position 446, causing the glutamic acid (E) at amino acid position 149 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
