The c.157A>G (p.T53A) alteration is located in exon 2 (coding exon 2) of the TOX2 gene. This alteration results from a A to G substitution at nucleotide position 157, causing the threonine (T) at amino acid position 53 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
