The c.46A>G (p.I16V) alteration is located in exon 3 (coding exon 2) of the TCAIM gene. This alteration results from a A to G substitution at nucleotide position 46, causing the isoleucine (I) at amino acid position 16 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
