Dec 18, 2023

The c.651T>G (p.N217K) alteration is located in exon 2 (coding exon 2) of the TRABD2A gene. This alteration results from a T to G substitution at nucleotide position 651, causing the asparagine (N) at amino acid position 217 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
