Ambry Genetics

Mar 29, 2024

The c.26C>T (p.S9L) alteration is located in exon 1 (coding exon 1) of the TTC14 gene. This alteration results from a C to T substitution at nucleotide position 26, causing the serine (S) at amino acid position 9 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
