Ambry Genetics

Nov 14, 2023

The c.34G>T (p.G12C) alteration is located in exon 1 (coding exon 1) of the GBX1 gene. This alteration results from a G to T substitution at nucleotide position 34, causing the glycine (G) at amino acid position 12 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
