Ambry Genetics

Oct 12, 2021

The c.83A>G (p.N28S) alteration is located in exon 1 (coding exon 1) of the TTC14 gene. This alteration results from a A to G substitution at nucleotide position 83, causing the asparagine (N) at amino acid position 28 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
