Collection Method: clinical testing

The c.295G>A (p.G99S) alteration is located in exon 4 (coding exon 3) of the TCAIM gene. This alteration results from a G to A substitution at nucleotide position 295, causing the glycine (G) at amino acid position 99 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
