The c.426A>T (p.K142N) alteration is located in exon 4 (coding exon 4) of the TP53TG5 gene. This alteration results from a A to T substitution at nucleotide position 426, causing the lysine (K) at amino acid position 142 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
