The c.425C>T (p.A142V) alteration is located in exon 3 (coding exon 3) of the TCF25 gene. This alteration results from a C to T substitution at nucleotide position 425, causing the alanine (A) at amino acid position 142 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
