Ambry Genetics

Dec 16, 2022

The c.290C>A (p.S97Y) alteration is located in exon 1 (coding exon 1) of the NTN3 gene. This alteration results from a C to A substitution at nucleotide position 290, causing the serine (S) at amino acid position 97 to be replaced by a tyrosine (Y). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
