Ambry Genetics

Aug 28, 2024

The c.29C>G (p.T10R) alteration is located in exon 1 (coding exon 1) of the SNAPC3 gene. This alteration results from a C to G substitution at nucleotide position 29, causing the threonine (T) at amino acid position 10 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
