Oct 03, 2022

The c.367T>G (p.W123G) alteration is located in exon 4 (coding exon 4) of the CHGB gene. This alteration results from a T to G substitution at nucleotide position 367, causing the tryptophan (W) at amino acid position 123 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
