Ambry Genetics

Feb 27, 2024

The c.587C>G (p.T196R) alteration is located in exon 2 (coding exon 2) of the SEZ6L gene. This alteration results from a C to G substitution at nucleotide position 587, causing the threonine (T) at amino acid position 196 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
