The c.466A>G (p.I156V) alteration is located in exon 7 (coding exon 7) of the TATDN3 gene. This alteration results from a A to G substitution at nucleotide position 466, causing the isoleucine (I) at amino acid position 156 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
