Ambry Genetics

Dec 28, 2023

The c.1396G>C (p.G466R) alteration is located in exon 3 (coding exon 3) of the SPTY2D1 gene. This alteration results from a G to C substitution at nucleotide position 1396, causing the glycine (G) at amino acid position 466 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
