Ambry Genetics

Jun 18, 2021

The c.53T>C (p.L18P) alteration is located in exon 1 (coding exon 1) of the TACO1 gene. This alteration results from a T to C substitution at nucleotide position 53, causing the leucine (L) at amino acid position 18 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
