Collection Method:clinical testing

The c.22G>T (p.G8C) alteration is located in exon 1 (coding exon 1) of the VSTM2B gene. This alteration results from a G to T substitution at nucleotide position 22, causing the glycine (G) at amino acid position 8 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
