Ambry Genetics

Apr 07, 2022

The c.323A>G (p.N108S) alteration is located in exon 5 (coding exon 5) of the SSBP3 gene. This alteration results from a A to G substitution at nucleotide position 323, causing the asparagine (N) at amino acid position 108 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
