Feb 28, 2024

The c.167A>G (p.Q56R) alteration is located in exon 4 (coding exon 3) of the TRABD gene. This alteration results from a A to G substitution at nucleotide position 167, causing the glutamine (Q) at amino acid position 56 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
