The c.2555C>T (p.A852V) alteration is located in exon 16 (coding exon 15) of the TRAK2 gene. This alteration results from a C to T substitution at nucleotide position 2555, causing the alanine (A) at amino acid position 852 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
