Ambry Genetics

Nov 10, 2022

The c.643A>G (p.S215G) alteration is located in exon 6 (coding exon 6) of the CLYBL gene. This alteration results from a A to G substitution at nucleotide position 643, causing the serine (S) at amino acid position 215 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
